Update to make compatible with all command maps

CB 1.7.2-R0.3 changes commandmap structure and commands in general,
providing the ability for server admins to prioritize commands however
they wish.

The new system in Bukkit allows for server admins to define a specific
plugin's commands as the priority (So they could, for instance, define /f
to always use factions regardless of what plugin got there first). Thus,
there is no need for the system of ninja-prioritizing all mcore commands
anymore! :)
