FPSdrawComponent Update

Put back the timer that i removed earlier, since i couln't get
'KeyRelease' or something like that to work...
Changed the timer slightly and combined it with the boolean, so you can
enable/disable it by clicking, but the timer will make sure there is a
small window so the boolean wont get switched 60 times per second. (max
1 time each 0.5 seconds)
