updated the REPO variable so it has the parent dir of .git, not .git itself

My setup is just a git remote, no gitweb, no gitosis, just git

Messages that appeared in Hipchat were as follows:

Brian Fehrle pushed to branch master of .git
- added permissions file for the database (c210b83)

With the update now looks like this:
Brian Fehrle pushed to branch master of ReleaseManagement
- added release 42.5 scripts (f672173)
