Looking through our command code after a long hiatus, I realized that it was pretty much awful. So here's part 1 of the command interpreter overhaul.

- 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.
