Command: load
Argument: <file>

If the object defined in 'file' isn't loaded, it will be. 'reset()' will
also be called in the object. If the object was loaded, nothing will happen.

This command is implemented by calling a (non existing) function in the
object, and that way forced to be loaded.

It is NOT implemented by teleporting the wizard to the object, which would
also force the object to load (and afterwards teleporting the wizard back
again).

The advantage of calling a (non existing) function is, that the wizard keeps
in distance and if errors occure through loading the wizard simply gets
error messages of the failed loading, not of moving there.

Rooms can also be loaded by just walking to them. That has exactly the
same effect.
