Better thirdperson for CS:GO

I know constantly re-checking for first/thirdperson if the game is cs:go or not isn't really that good, but since the include also gets used by other last requests not compiled inside of this hosties plugin I don't want to risk breaking these (for example by relying on one of the plugin's booleans or w/e here). Feel free to change things though
Better thirdperson for CS:GO
Merge remote-tracking branch 'upstream/master'
Binary with thirdperson changes

Also made it only look for the sv_allow_thirdperson in cs:go like you
asked
Merge pull request #3 from MVermue/master
