Changing commit from commit -> push

After chats with people such as @phamann and @adamnfish - it seems the pre-commit hook really gets in the way of certain workflows (i.e. Committing loads and rebasing later). Basically it caters for the simplest use of git only.

I also understand that the hook is necessary so eagle-eye @kaelig et al don't have to rummage through the SasS finding formatting problems.

This caters for both I feel.
