Blame output is now colored according to Commit (default), Author or
Age. Both Commit and Author output uses random colors whereas Age uses a
single color with varying tints applied to indicate the age.  White
indicates the eldest commit with the tint darkening as the commits get
younger.

The mirror executor will fetch ref updates for repository mirrors.  This
feature is disabled by default and can be enabled by setting
git.enableMirroring=true.  The period between update checks is
configurable, but it is global.  An individual rpeository may not set
it's own update schedule.

Requirements:
1. you must manually clone the repository using native git
   git clone --mirror git://somewhere.com/myrepo.git
2. the "origin" remote must be the mirror source
3. the "origin" repository must be accessible without authentication OR
   the credentials must be embedded in the origin url (not recommended)

Notes:
1. "origin" SSH urls are untested and not likely to work
2. mirrors cloned while Gitblit is running are likely to require
   clearing the gitblit cache (link on the repositories page of an
   administrator account)
3. Gitblit will automatically repair any invalid fetch refspecs with a
   "//" sequence.

All WikiLinks must be specified relative to the root of the repository.
The displayed link text is stripped to just the document name. Spaces in
the document name are replaced with '-' characters; this is consistent with
wiki syntax and Github.

Renamed pushlog to reflog to better match it's current and future purpose.
Split PushesPanel into ReflogPanel and DigestsPanel.
Overhauled project pages and gave them a coherent purpose from the dashboard.

* Properly support timezone-based date groupings
* Polish css for the major browsers on Win & Linux
* Use Gitblit constants for refs instead of JGit constants

This is a work-in-progress and is mostly working like I want, but will require
some refactoring to make it even more useful and less complex.

This will probably be merged into a refined, single multi-protocol
url panel.

This will probably be refined some more to merge the http/https and git urls
into a single url panel.

This is a massive commit which reorganizes the entire project structure
(although it is still monolithic), removes the Build classes, and
switches to Moxie, a smarter Ant build tookit based on the original
Gitblit Build classes.

The Ant build script will likely require additional fine-tuning, but
this is big step forward.

Present the mutable permissions by default.  Allow the administrator or
owner to toggle the displayed permissions to see how the user
and team permissions are applied to a repository.
