This patch adds a setting, 'web.activityDurationMaximum', that specifies the
maximum number of days of activity that may be requested. The default value is
30. When the number of days requested exceeds this value, the request is
handled as though the maximum value was requested.

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.

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.

feature: when LDAP user synchronization is enabled, one can configure GitBlit to delete all LDAP users from the backing user service that are no longer existent in LDAP. By now LDAP users that were deleted still appeared in the GitBlit user list.

Also hooked-up GC settings in the Manager.

If this feature is enabled then permitted users can automatically create a
repository when pushing to one that does not yet exist.  Permitted users
are administrators and any user with the CREATE role.

If the pushing account is an administrator, the created repository may be
located in any folder/project space.  This reposiory will inherit the server's
default access restriction and authorization control.  The repository owner
will be the pushing account.

If the pushing account is a regular user with the CREATE role, the repository
can only be located in the account's personal folder (~username/myrepo.git).
This repository will be VIEW restricted and accessible by NAMED users.  The
repository owner will be the pushing account.
