Movement Code Refactoring Complete

....more or less, anyway. I think I've finally managed to get the movement code refactored and working in a manner similar to what it used to be so long ago. The next step is to return to what was being worked on before that (effects and classes) and continue the never-ending RingMUD quest.

On a side note, the code is now on a subversion repository as I find it less annoying and less complicated than CVS.
