Our command evaluation now mirrors MUX2's. It was kind of weird before now, I'm not really sure how it got so out of order. In any case, I'm no longer ashamed of our command handler code. Hooray.
- The command handler has been drastically simplified. We were doing way too much processing in the handler that should have been done in the individual command functions themselves.
- The 'cdat' dict we were previously passing around has been replaced with a Command object that has useful methods for performing some of the parsing command functions will probably want to do from time to time.
- All commands were updated to use the new Command object, tested, and cleaned up in general.
- A lot of formatting was cleaned up.
- A lot of previously un-found bugs and limitations were fixed.
- The 'page' command has been broken out into its own file, since it's going to have a number of functions that would otherwise clutter commands/general.py.
Expect a commit (probably later today) that will clean up the second half of cmdhandler.py.
