Hot key toggle to freeze game without seeing stats - just stop all balls, pups.

[andygett]

Pick toggle event - space bar? f key?
something like (this is kind of old)...
def function getRunModeFromUserInput(self, runMode)
if K_f, return "f"
if runMode = f, show text Press f tounfreeze
else:
self.showUserLevelOnClearScreen()
On resume, extend powerups by pauseDuration like rmPAUSE
But create rmFREEZE= 2**3 or something instead of "f"
