endDependencyLoading that was used for starting to load the deferred
connector bundle is only called during regular application init if the
theme wasn't yet loaded when the initial UIDL request finished.

With this patch, the bundle is instead set to be loaded after the
initial UIDL message has been completely processed.

Fixes #4763

To ensure the resource is automatically closed

* Fix exception when no columns are shown or all columns are frozen

Fixes #8329

* Fix partial state change handling of JavaScript components

In ace0e324b6 (Use diffstate for JS connectors) 
partial state change handling for JavaScript components was introduced, but the
setNativeState method in JavaScriptConnectorHelper was not adjusted.
By removing the cleanup code from the updateNativeState method it can 
be ensured that the non-changed properties are still present on the state object.

* Add test for preserving untouched JS state fields

* Add initial implementation of TreeGrid

* Refactor TreeGrid and related classes

* Fix potential class cast exception in TreeGrid#getDataProvider

A login page you want to redirect to is typically in the webapp root,
which you can now refer to as "Vaadin-Refresh: context://login.html"

* Fix java packaging order (#106)

Closes vaadin/archetypes#113

* Use proper UTF-8 encoding for Content-Disposition filenames (#19527) (#6607)

* Enable changing the backing bean for BeanItem (#4302) (#77)

When storing a bean to the database, you typically get a new and updated
bean instance back. By allowing to change the bean instance, we make it
possible to just update the single BeanItem instance which can be used
in many places.

* Make AtmospherePushConnection methods public (#7973)

There is no sensible way to use a custom version of APC, so protected
access does not help in any way to access the underlying resource and/or
connected UI.

* Use correct indexes in multiselect checkboxes after removing rows (#8072)

Fixes #8011

* Fix removal of hidden Grid columns (#8071)

* Apply generalization of drag and drop extensions in #8440

* Override javadocs to be more specific

* Reduce ComboBox initial requests

Use initial fetched data on client side,
do not request data from server side for each time popup is opened.
Fixed initial filter being null for ComboBox on DataProvider,
causing unnecessary size & fetch for not-changed filter.
Fixed ComboBox sending default filter unnecessarily to server.
Fixed wrong page indexing in VComboBox -> ComboBoxConnector.

Fixes #8496
Fixes vaadin/framework8-issues#488

* Fix last item missing

When pageLength was 0 and nullSelectionAllowed,
the last item was not shown. Tried to sensify the API
for total suggestions versus total suggestions + null selection item.

* Fix ComboBox selected item updates

Handles changing of ItemCaptionGenerator or ItemIconGenerator,
need to update the selected item caption and icon separately.
Previously it worked because all data was sent all the time to client.
Doesn't fix the issue, when selected item is updated with refreshItem(),
and it is not on the active range that will be sent to client.
For that, ComboBox would need a separate notification about item update.

When adding (readding) a column the column should also be
added to footer as it will be removed and iterator will request footer for it.

* Add test for re-add column (#590)

* Fixed compilation problem.
Too little sleep for a friday evening...

Fixes  #8405

Fixes #8371

Fixes #8373

* Include FontAwesome by default for easier migration
* Fix JSComponentLoadingIndicatorTest

Fixes #7979
Addresses part of #8219

Running formatter:format will format all files in a submodule using an
embedded Eclipse compiler (based on Neon SR1)
according to the regular formatting settings file.

Fixes #8366

* Introduce empty selection functionality for NativeSelect.

Fixes vaadin/framework8-issues#545

* Allow to disable user selection in the grid model.

Fixes vaadin/framework8-issues#546

* Add DataProvider refreshItem for single item update

based on their id. This can be used to simulate stale objects from an actual
backend.

* Add refresh logic to Grid SelectionModels

* Fix documentation for refreshing an item

* Improve introduction chapter, minor clarifications

* Merge remote-tracking branch 'origin/master' into 287_refresh_items

* Add missing parameters in unit tests

Note that not all browsers yet support HTML imports. If a polyfill
is needed to load HTML imports, it must be loaded before HTML Imports
can be loaded. There is no automatic loading of any polyfills.

Cannot overload the same create method for this purpose since it
conflicts with T... overload. Each case is instead given its own
descriptive but still discoverable method name.

* Fix absolute layout component sizing on size change (#8255, #8256, #8257)

Changing from relative to defined size leaves the component positioned wrong,
also changing from defined size to relative size leaves the component in the
wrong position with the wrong size.

Change makes the wrapper rerun setChildWidgetPosition() that adds/removes
necessary css definitions to/from the cssPosition String.

* Clean test sources according to review.

* Overload AbstarctComponent.setDescription() with content mode parameter

Fixes #8185

* Introduce DateTimeFile and InlineDateTimeField.

Fixes #8132

* Correct and provide declarative tests.

* Provide a date converter and UI tests.

* Change BackEndDataProvider into an interface

BackEndDataProvider is now an interface with methods for setting
sorting options based on SortOrder instances. 

AbstractBackEndDataProvider stores sorting options, combines them with
the sorting provided in the query and invokes its own abstract fetch and
size methods.

CallbackDataProvider implements a BackEndDataProvider based on two
lambdas.

This is one of many steps towards #8245

* Add getHeaderCellByCaption method to tb-api GridElement

* Added support for HTML5 push/replaceState for proper deep linkin features

* Automated test script now works at least on chrome

Tested a workaround with javascript based window.location.href fetch,
but that don’t seem to work stable enough.

* Add "deselect allowed" feature to the Grid.

Fixes #8149

Fixes #7005

* Replace Listing with HasDataProvider and HasFilterableDataProvider

The type parameters of the Listing interface does in practice mean that
it isn't useful for anything. This patch replaces that interface with
separate types for components that require filterable data providers and
components that support any kind of data provider.

The setItem methods are extracted to a common interface that is also
directly implemented by AbstractListing.
