Implemented Command Processor (#375)

* Added CommandConsole and CommandProcessor Interface

* Added two commands, ListPlayers and Stop

* Registered commands with CommandConsole

* Added request for console from main.

Made help prompt not print after requesting help...

* Moved some files around

You didn't see anything

* Bug fix

* swap `break;` for `continue;`

* *cough* bug fix
