Change 'freelook' to user cvar

[ijon]

pretty self-explanatory, move freelook from a server cvar to a user cvar, nothing else to it

checking for freelook as a server cvar is not useful in multiplayer, where one player could have freelook on and another could have it off

reason this would be useful is so that my recoil scripts, which check if the player has freelook on before applying vertical recoil, wouldn't potentially break multiplayer

I think it was for precisely that reason that it *IS* a server CVAR!
