* Fixed touch scrolling issue in Surface and WP devices (#18737)

Fixed by using pointerevents instead of touchevents when the browser is
IE11,
or Edge. Also added touch-action: none; css rules into escalator.css to
prevent
default touch behaviour on IE11 and Edge. Does not affect IE8 to IE10
browsers,
behaviour on those will stay the same as before the fix.

No new unit tests since we do not have automatic touch testing
possibilities yet.
Please test manually with Surface: IE11 and Edge, use for example

will make the menu appear on hover - i.e when mousing over on desktop,
when tapping on touch devices (which also triggers hover).

Added API setPopupWidth(String) to ComboBox. The suggestion pop-up now
has three different width modes:

1. Legacy "null"-mode: width is determined by the longest item
caption for each page. This looks & feels like the old implementation.
This is the default mode

2. Relative to the ComboBox. e.g. 100%

3. fixed width using any CSS definition

This change also cleans up some redundant POM metaadata.

Even though Maven documentation does not list it, also the organization
section is inherited to the effective POM.

pom-template.xml is still in the project for a longer description and a
repositories section until publishing to staging is cleaned up.

This patch refactors how unpacking of dependencies is handled.
It now uses a more generic configuration on top level as well as
updates the phase where the extraction happens. This way the source
plugin configuration remains small
