This change makes it so /kick, /ban, and /map open the already created methods for displaying their menus when there are no args.
The reason for the feature is to take advantage of menus that already exist and to make the commands easier to use.
The client == 0 check prevents them from opening if it was ran via rcon, sm_rcon, or server command. Client auth is also checked because its a registered admin command.
Usage params will display if client == 0 and args < min
For example, a moderator wants to change a map, instead of running through the admin menu, they can instead type just /map to display available maps and choose one.
If a mod wants to quickly ban or kick someone without having to either run through the admin menu or type it out, they could then type the corresponding commands with no args to open the menus.
Various minor things done to project files
