Support git 2.9's new hooksPath configuration variable

[thegranddesign]

In git 2.9, a new hooksPath configuration variable was added which is a perfect companion to overcommit. It lets you keep a common directory where hooks can reside and you never have to ever worry about keeping your hooks in sync between your repositories.

It seems as though a $REPO_ROOT/.git/hooks is hard coded where overcommit's hooks look for the base overcommit script.

I'd love to see support for overcommit looking to see if git's hooksPath configuration option was set and, if so, looking for the overcommit script in that location.
