Code cleanup
(finally) renamed the game type list

This has been in the plan for a while but given a recent config breaking
change, we might as well break everything in one hit.
Added nuget package for Myrcon.Protocols.Frostbite
Fixed unit tests to work with common-game-type

Ironically fixing the issue the class itself was trying to prevent.
Packages now only cached if they have Procon tag

Occurred to me speaking to nick that if some one adds nuget.org then
Procon would attempt to cache their entire repository.
