Improved the GUI manager.

Browse Source 
* NEW: reformatted the code a little bit to make it more readable.
* NEW: added Javadoc when it was missing.
* NEW: changed the name of the fallback action method in `ActionGui`, from `onAction_unknown` to `unknown_action` (coherence of the methods names).
* NEW: the action methods (both declared and unknown) can now take an extra argument: the triggered InventoryClickEvent. This argument is completely optional, so this will not break any code, and if the event is not needed, it can just be skipped.
* NEW: renamed the setData(int, int) method to setDataShape(int, int), because this method does not actually set any data.
