Mac v6 beta test

[Admins]

The new version 5.324 has been uploaded to http://www.graalonline.com/downloads/beta/Graal_mac.zip :
- Fixed several shortcuts and input keys on internal keyboards
- Added undo/redo functionality to GuiMLTextEditCtrl, by default 16 undo steps, you can increase by setting undostacksize = number; the undo/redo is working with normal shortcuts: Ctrl+Z for undo, Ctrl+Y or Ctrl+Shift+Z for redo
- Support for more body colors on client-side (you can e.g. do for (i=0; i<5; i++) player.colors[i] = "indigo"); server-side support will be added when all clients are switched to v6; you will appear black to other players when using the extended colors; all html colors are supported (20 default colors + 143 html colors)
- Fixed the indigo html color
