GetCVar returns a per-player copy of the requested cvar, which is only
used to have separate values for each player - changes are propagated To
it, but not From it.
writing to this cvar is only useful if you know what the actual new
value is going to be & want the cvar to update Immediately.
(in this case, the cvar needs to be updated before A_SetHelpText so the
displayed spray name is correct)
FindCVar returns the actual cvar for the local player. changes to this
cvar Are propagated to other clients.
