Subject: [PATCH] refactor: Change the way that all hooks work

Move hooks to a dedicated module.
This allows for greater flexibility and easier editing.

TODO: Make hook handling neater (possibly through parsing the hook
	script to read an "hook-to" marker that allows for automated
	loading of properly formatted hook functions)
