Better detection for gerrit repositories

I use Gerrit with Smartgit for many repos but Gerrit was never detected by Smartgit despite claimed support.

Documentation says:

SmartGit will detect a remote as being connected to Gerrit, if:

• .git/hooks/commit-msg exists; and
• there is only one remote overall or it's the only remote connecting to port 29418 (default Gerrit SSH port)

The second condition is clearly too restrictive. Repos I work with use port 29420 so I'm doomed to never see them detected with current detection method.
