preenfm2: when exiting screen saver, ignore button click until screen on

[solipsvs]

when i press a button to exit the screen saver, it also makes a change to the voice.  i request that any button click or turn off the knob does nothing except awaken the synth until the screen is on.

Not easy to do, as the code responsible to modify values has no idea about the screensaver.
So you can put that of the list of known bugs.
Pressing a known key (top left/ engine one) to exit screensaver mode is safe as it cannot change any value.
