Beginning of new command parsing interface
This adds commands.py, with a primary interface dispatch(args)
Dispatch searches a table of known commands, handles switches, sets up
a repo object if appropriate, and dispatches the command.
It also handles KeyboardInterrupt and can handle similar exceptions in
the future.
If the command is unknown, it falls through to the current command handler.
Commands currently handled by the new scheme: help, init, and annotate
