Hardcore and Server Browsers

Hardcore game modes need to be added on official servers and available for any potential server browsers.  It will fix any complaints for TTK complaints as well as keep the hardcore fans happy.  It's a must have IMO.  

A server browser would be super nice to figure out custom servers, map rotations and specific game modes easier.  Sometimes you get the same maps 3 or 4x in a row, or never get a certain game mode when everything is turned on.
