Bug fixes

This pull request fixes some of the issues reported in #7.

The look command now works, I have at least not been able to make it crash after the changes. Get should also work. In order to make "get" work I had to make it look up items just by the first word submitted. I am not sure this is the way it is intended to work, but that was how it was done in the "look" command, so at least it is consistent.

I also removed a .swp-file that had made it's way into the repo.
