Mud Designer:

- Currency Editor no longer adds duplicate currencies when saved.
 - Currency Editor now overwrites existing currencies.
 - Fixed Currency Editor looking for .xml filetypes instead of .currency filetypes. Saved Currencies now show up in the currency list

Mud Engine:
 - Removed IsSafe property from BaseObject as not all objects will need this property.
 - Added IsSafe property to Zone.cs
 - Added IsSafe property to Room.cs.
