Add uninstall option to git mit-install

[robolson]

Is your feature request related to a problem? Please describe.
I added git-mit to many of repositories on my computer. I have chosen to stop using git-mit but the uninstallation procedure is manual. If git-mit provides an install command, it is logical that it would also provide an uninstall.

Describe the solution you'd like
A command like git mit-install --uninstall that will remove the git hooks put in place by git-mit.

Cool, will look at this.

Until I get round to this, here's an uninstall guide:

You can on a per repo basis just delete the files in the git hooks directory usually .git/hooks

If you installed them globally we add them using the templateDir. You can remove this config or remove the files from the hooks folder
