[Fluxus] commits: keypress playback pause

[gabor papp]

hi,

i committed the changes that made my makeart presentation possible, 
where i was typing text and code during the talk. you might know that 
fluxus is capable of saving and replaying keypresses using the -r and -p 
commandline options. these modifications disable the keyboard while the 
keypress file is played back, so you can fake typing. pressing f12 
pauses the playback and let you type, until you press f12 again which 
resumes playback.

best,
gabor
