Each Gravatar thumbnail is now a link to the Gitblit Gravatar profile
page.  This page displays some of the profile information and contains a
link to the full Gravatar profile.

Activity page links now launch a new window/tab instead of targeting
"self" since it can be expensive to requery the activity information.

Repository owners no longer have to be explicitly selected to grant
them access to Git, feeds, and zip downloads. Idea from Github/dadalar.

Added setting metadata. Added server status rpc. Improved setting tab in
Manager.

Added new request type to retrieve Gitblit settings to implement the
password preferences (minLength, storage type) and federation sets.

This unit test is not part of the suite since it requires firing up
gitblit, commiting, and stopping gitblit.  This is the first step in
evolving unit testing of cloning/pushing.

If an object id was not specified Gitblit used HEAD to perform the
operation.  This breaks under some conditions like working with a
repository that does not have any commits on master but does have
commits on a vcs-import branch.

The new approach is to centralize the resolution of unspecified object
ids to a common method which resolves HEAD first but uses the most
recently modified branch if HEAD points to nothing.

This commit also includes a non-functional method for creating an empty
branch. I couldn't figure out how to make JGit create an orphaned
branch.

* Build script overhaul including building & publishing GO, WAR, Docs,
and Site.
* Restored JGit 0.12.1 dependency and backported Blame.  Got tired of
waiting for JGit 1.0.0 Maven artifacts.
* Changed Summary Page layout
* Optional cookie authentication
* Added icons for log, tags, and branches panels.
* Show last commit author and short message on branches panel.
* Unit testing.
* Documentation.

Replaced servlet container basic authentication with a custom servlet
filter which performs the same function.  The advantage to this is
that the servlet container is now divorced from the webapp.

The login service (realm) also simplified a great deal and removes its
Jetty dependencies.

Additionally, the basic authorization pop-up will be displayed as
needed based on the repository's access restriction.  This was
necessary for view-restricted repositories with the RSS feature.  Its
also necessary for completely open repositories as before it would
prompt for credentials.

Improved feed syndication feature.
