Add an api.php to document the hooks

This is a really good start.

From what I can tell by searching the code for 'invoke', there's also a hook_fasttoggle_toggle(). A few other things that need improving:

1. +++ b/drupal/sites/all/modules/contrib/fasttoggle/fasttoggle.api.php

   Should be an imperative verb, so 'Return options...'.

   This needs documenting too.

   Missing @return here too.

Missing documentation is a bug BTW...

Fixed in 7.x-1.3.
