Quake/Battle Royale Announcer Lines 2018-07-29

Put the non-used ones in their own folder.
Added a minimal version of the game_sounds file which doesn't include the non-random version of the sound replacement names.

Seems all the last man standing lines were unused, so they've been removed. Also removed the KS files from the main folder.
Moved some less desirable lines as well as the KS lines to the scrapped folder.

Seems valve has the arena countdown using roundEnd sound scripts instead of roundStart. Really messed me up since it's the start of the round count down.
