New parser + command structure is 95% complete. Argument validation is

a lot better now. There shouldn't be any more crashes due to missing
error checking, as the error checking is done by the parser now, instead
of by each command (so I can't forget it now). Also, now that the commands
are stored in an array, I can start on tab-completion for commands.

TODO: validate multi-byte arguments (e.g. the data for the "ram" command).
Currently the command works, but will accept values that don't fit into
a byte. Also validate multi-word arguments, though we don't have any
commands that use them yet.
