Add the ability to disable autogit via config setting.

Hello Pedro!

First off, this module is exactly what we needed to build, so thank you very much for sharing it.

However, we want to turn off autogit for our local dev instances, so we needed to add a flag to do that.

If you're ok with it, can we merge this back in so that we can use your version for our project?

This fixes #26

The method you used works fine if you just use the panel. However, if you're calling AutoGit from a controller or somewhere else, you would run into errors, as there's no longer an instance, which can be accessed.

The Autogit class is not that big, by adding your code to the functions, my scenario continues working.

Thank you! I just published a new version which includes this feature.
