setting a cvar with "set" or without

[IzNoGoD]

If some var is already set as a cvar, it doesnt need set.
If it is not, cod will auto-assume its a command, thus it needs set.

This way you can fuck with players that do /quit a lot, by setclientcvar("quit","hehehe");. The client then would need to do /cmd quit in order to actually quit the game.

After the first set command of a cvar, future operations will not require the "set" prefix.
