From now on, ideally any function with "get" in the name should always
return a valid value. A function with "find" in the name, however, does
the same thing, but may also return an invalid result such as an error
code.
I need to devise a way to update the clients about changes to their
characters directly from the lua scripts. This isn't too important per se,
but the pattern will be important for the monster and trigger systems.
