Problem with a repository that has index.php file

This is the workaround for the issue https://github.com/klaussilveira/gitlist/issues/523

The problem here is when the repository contains a index.php and of course we all know that apache server's default is to set its default index file to index.php, the gitlist doesn't list this index.php and the work around that I did is to change the directory index so index.php will be listed in the repository and not executed by the interpreter.

This is just a workaround and I am not pushing this workaround to be the best solution :)
