Incremented redmine_git_hosting version from 0.4.4x => 0.4.5x

This is a bugfix release.  Changes in this release:

1) Fixed missed case for Redmine 1.1 compatibility (mirror functionality)
2) Fixed bad interaction between cron cleanup of /tmp and access to
   gitolite-admin repository in /tmp.  Behavior could cause user
   keys to appear to be deleted, even though they remain in the redmine
   database.
