Fixing the licensing scripts

- Fixed shell glob limitation that was failing license updates on big commits
	- Hook will now force user to re-commit after updating the licenses (pre-commit hook can't update and commit in the same process)
	- Moved all scripts to bash/zsh
	- Separated the license utilities in a separate python module to avoid copying code
