Commands now require a setup to define their permission, player/console
status, description and any parameters they have. This is also where any
subcommands are created if they exist.
Each command automatically has a help subcommand. This is used to
display help. This will also recursively go to any other sub commands
and get help from them.
Note that getUsage() now *only* shows the command and any sub commands.
It turns out that Bukkit requires this to start with a / because it
actually uses this in its own help system and the server will not start
if it is not in the right format. Therefore I split off parameters into
their own string. This also enables them to be translatable.
Everything should work at this point. It's just waiting on the locale
system to work to display the strings in the locale files.
Changed the response for canUse to return an error code because the
error could be different depending on the reason. For tabComplete no
error is shown, but for commands, the error can be shown.
Implemented the invite and uninvite commands and filled in the team
command.
