Version 0.6.4

This was a tough update to create, but I think I managed to work out all of the bugs.  The pink engine now includes support for moving objects, meaning you can create full-fledged NPCs. A new testing room has been added, where you can see NPCs wandering about. 

The current list of movement options is still somewhat limited, which is what version 0.6.5 will focus on. 0.6.5 is planned to be the final update for 0.6 (unless I discover bugs, of course), with 0.7 focusing on being able to create cutscenes. When 0.6.5 is done, I will also be updating the documentation to describe all the new features.
