Currently the LDAP user service will not dereference aliases when
searching for groups. This patch enables dereferencing aliases for the
group search. This is benefitial if groups are defined in the DIT in a
common place but only certain ones shall play a role in Gitblit. These
can now be linked under a group that can be provided as search base for
groups, without having to recreate the existing groups under the search
base.

In addition, the new doSearch() method implemented in this patch also
limits the attributes returned for the group search to the "cn"
attribute, which is the only one used. That prevents returning all the
members of the result groups, which can be a lot.

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.

The graph is generated server-side and therefore requires that the
commit table row height be fixed and match the row height of the
servlet.  There will be layout misalignment if remotes refs are
displayed.  Perhaps this can be improved in the future.

Add a new class, HtpasswdUserService, which performs authentication
against a text file created with the Apache 'htpasswd' program.

Added dependency on commons-codec:1.7

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.
