API change in hook-adding

[xoft]

Wow, I've rewritten the hook system almost completely. But it works! I just hope I didn't make some stupid mistake in there, go ahead and test it.

Don't forget, the recommended way of adding hooks is

cPluginManager.AddHook(HOOK_TYPE, CallbackFunction);

Note the dot instead of a colon, the AddHook function is "static" - it doesn't need a cPluginManager instance (since there's only one anyway). Colon will be accepted, too, but is deprecated.

I'll update the HookNotify and the Core plugins for the new API now.
