Use registered commands for help display of permissions

[suresttexas00]

TODO we should really base permission on the actual command permission, and not a (potentially inconsistent) api.registerHelp() entry!

commands.py

                            # i is each help item, like:
                            # ('/bmlist', 'List bookmark names', None)
                            for i in group:
                                command, args, permission = i[0].split(" ")[0], "", None
                                if i[0].split(" ") > 1:
                                    # if there are args after the command
                                    args = getargsafter(i[0].split(" "), 1)
                                # TODO we should really base permission on the
                                # actual command permission, and not a
                                # (potentially inconsistent) help entry!

                                # will only display is player has permission
                                print(i[2], player.hasPermission(i[2]))
                                if not player.hasPermission(i[2]):

The registerHelp item can be deprecated in a backwards compatible manner since it should properly match it's command anyway!
