0.2.0:
 - cleaned-up the nasty source a bit,
 - new frame synchronisation mechanism -- invalidated -r param by a lot,
 - bandwith saver - now program will only send update request to buttons which text actually changed,
 - added -t and -s optional params -- equivalents of ffmpeg preinput -ss option and postinput -t, one skips forward the selected video, the other sets duration of playback.
 - added versioning -- 0.1.0 didn't displayed it because I haven't expected to work on it further. But yet, the temptation was too strong...
 
0.1.9:
 -- this is experimental colour version, which is abandoned due to unsufficient results vs. resources required to improve upon it. It's actually downstream from 0.2.0 version btw.
