* Strip leading group name from repositories page.
* Put topbars on all pages.
* Properly sort repositories in all locations.
* White Gitblit logo.

This allows custom implementations to store their settings alongside the
Gitblit GO or WAR settings while remaining unit-testable.

HEAD is now properly reset if mirroring is enabled.  Updated the
federation pull status enum to include no change and mirrored states.

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.

Jetty 7.4.4 introduces a fix to correct url generation. Unfortunately,
this "fix" creates a bug for resolving the root page. Evidently the bug
may really be in Wicket.

* Renamed prunsrv.exe to gitblit.exe so that task manager shows
more useful information.

* Documented how to configure the service to use a server VM, if a JDK
is present.

* Clarified SSL certificate generation and configuration in light of the
hostname verificiation that JGit currently does despite
the http.sslVerify=false setting.

* Added some troubleshooting information related to filesystem
permissions and reading repositories.

* Switched from JavaService to Apache Commons Daemon.  Not sure what
happened to JavaService as it stopped working for me on Windows 7 with
Java 1.6.0_26.  Commons Daemon accomplishes the same thing and offers a
nice service control utility.

* 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.

Reorganization of resources. Dropped most hard-coded webapp
configuration in favor of common web.xml file. Still contemplating
configuring git servlet from web.xml too.

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.
