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

* 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.

The JGit team is now publishing 0.12.1 artifacts on the Eclipse Maven
site. Yeah! That was the last missing piece for a slick Git:Blit
deployment. The build has been reworked to download from Eclipse and
to also download source and javadoc jars for setting up a development
environment.

Made the log4j pattern configurable by operating system.
Moved Markdown utils to their own class since I need StringUtils for
Build and that introduced a chicken-and-egg scenario.

Settings access has been abstracted and the way is becoming clear to
offer a WAR build in addition to the integrated server stack.  Util
methods moved around.

This seems to improve page loading times.
