Bukkit

+ Much better default configuration: It took me some days, but now there is an well better default configuration, so you can test it a lot better before you customize it to your wishes.
+ Added /fakecmd: /fakecmd will allow you to let players execute "fakecommands" wich are not registered to Bukkits command registry.
Most alias-plugins and TownyChat for example uses such "fakecommands", so if you want to let players execute that commands via. the GUI's you need to use /fakecmd player ImAFakeCommand
This *may* also allows you to execute BungeeCord Commands with TownyWands!

• Coming Soon: A full working /gui command wich can:

Create new GUI's
Change existing GUI's
Delete GUI's
Maybe change items, that feature would probably needs some more time.

• /vsign currenlty only works on 1.8 versions! (1.7 Backport will follow if possible & requested!)
  
• The compat.-check may not work on all situations but at the most it will do its job well!
  
• The Translation takes now ages (500 seconds or more per GUI) due to the new default config. if you have the auto-translation enabled.
  
• Some translations may shows Unicode values instead of UTF-8 text ingame.... *maybe fixed that already*

(MC 1.6.4 ONLY) If you're on 1.6.4 don't use enchanted items!
It will crash players when they hover over the item!

I have found no other bugs so far, if you find some, please report them to me and i'll fix them!
