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.

Adding LaunchLevelPlaybackVideoRecorderSmall, which inherits from
LaunchLevelPlaybackVideoRecorder, and only has a small section of code in a
'static' block.

Adding some really interesting games that were recorded in real time.

Changing some dimensions in SmallCanvasConstantOverrides; it looks much better
now.

In NextBlockDisplay, if the block image is too small for allocated canvas
space, chopping area from the top of image instead of from bottom. This fits
better with game layout, e.g. GameSidebar.
