[task/git-tools] Vastly expanded commit-msg hook.
This updated hook supports validates each line of the commit message confirms to the phpBB standards [1], there are two git config options which adjust the behaviour of the hook. They are: * phpbb.hooks.commit-msg.fatal: Set to false for the hook to allow commits with malformed structure, useful if you'll be squashing or editing the commits later. True is the default value. * phpbb.hooks.commit-msg.debug: Any integer value greater than 0 will increase the debugging verbosity of the hook, the default value is 0.
