Code needed for the precommit hook.

Adds two files that will need to be moved into the correct folders to work:

os_project/config -- needs to have one variable "PROFILE_DIRECTORY" set to the value of the profile folder, so "os_project," but renamed to its correct value and then moved to .git/hooks.

pre-commit -- needs to be moved from the base to .git/hooks.

drush turnip-init needs to be able to take care of these.
