grafx - Extensible Java Graphics Package Code

Adding class net.blockout.production.ScoreReporter. Not using it yet.

Moving HighScoreDisplay to GameScoreDisplay, which is now an interface, and
having GameSidebar implement that. I'm in the process of refactoring some
code.

Taking care of some very minor odds and ends; improving Javadoc and removing an
import statement that was not used in LevelPlayback.

Adding quick comment to LocalBlockoutBoard which describes that certain time
intervals are currently hard-coded.

Fixing FRAMES_PAST_EOF calculation.

Removing a TODO.txt item related to finding out the exact framerate of videos
coming from GoPro camera.

In ffmpeg-overlay.sh example config file, changing fps from 29.97 to 25, from
59.94 to 50. I'm not going to pretend that I know how drop frame timecode
works.

In script '.compile-video-base.sh', allowing environment variable 'VID_FPS' to
override the default of 50. Computing FRAMES_PAST_EOF based on that.

Taking out two TODO items that are already done. The "small profile", and some
test results for weighted strategy in "q best moves".

Adding script compile-video-small.sh.
