Fix Redmine not showing repository data

For some time, the git repository I am using to track changes for my Django-Management TextMate bundle was not working correctly in Redmine. I was able to connect it up using the settings, but was getting errors about the files not being found.

It turns out that git was not in my path. Putting a link from /usr/local/bin/git to /usr/bin/git fixed that all up.
