Added For Dee Demo

I added a zip with a demo of For Dee embedded in the client. For Dee is a four dimensional top down game that I am working on in which the player controls an instance of the unicorn named Dee and I will release it as a separate game eventually. The demo here is V0.0.0 and it will likely not be updated to any newer version that I release. The controls and such are in the README.txt of the zip.
