Implemented locks.

Browse source 
The main command to use is @lock, which accept three types of locks at the moment, and three types of keys:
 Locks: DefaultLock, UseLock, EnterLock
 Keys: ObjectIDs, Groups, Permissions
This offers the most useful functionality - stopping people from picking up things, blocking exits and stopping
anyone from using an object.
If the attributes lock_msg, use_lock_msg and enter_lock_msg are defined on the locked object, these will be used
as error messages instead of a standard one (so "the door is locked" instead of "you cannot traverse that exit").

Behind the scenes, there is a new module, src/locks.py that defines Keys and Locks. A Locks object is a collection
of Lock types. This is stored in the LOCKS attribute on objects. Each Lock contains a set of Keys that might be
of mixed type and which the player must match in order to pass the lock.
