Fixed #165, Fine tune fixes!

* Fixed an issue with the cooldown timing.
* Fixed issue with 'right click' using items under players.
* Some changes to the minimap control (ctrl + mouse wheel to
  change floors and tweaked the zoom/move speeds).
* Fixed some bugs in the trade module.
* Added new Spells table for spell related functions
  (Also added getSpellByName and getSpellByWords).
* Fixed an issue with follow/attack cancelling (wasn't calling
  onFollowChanged for updates in battle, etc).
