This is a much better way to work with our commands dynamically. It

allows for localized description strings, aliases, etc.

With this addition, our "ugly alias" method in CommandPreProcessEvent is
no longer needed, nor is our alias map.

This also makes us more friendly with Essentials - if Essentials is
enabled, the /repair command will be changed to /mcrepair for
compatibility reasons.
