Removed vim .swp file from repo
Removed invalid dict lookup in the get command

The current room the user is in is stored in self.room, so it is not
neccessary to look up dictionaries to find the room objects. This avoids
the incorrect dictionary lookups that were used.
Fixed player and monster iteration in look command

self.room.players and monsters are lists, so it is possible to iterate
over them in the manner done in this commit.
