grafx - Extensible Java Graphics Package Code

Adding DummyGamestateListener.

Finished implementing all levels 1 through 24, inclusive. I think this will
be enough. Default computer level changes to 21 (because the level number
changed as well). Orange and white color flip in game text, to encourage
viewing white stuff.

Changing from a green well to an orange well to be easier on the eyes.

Changing some formatting in ScoreGenerator.

In net.blockout.production.BlockImage, offering better handling of color
overrides.

Adding data/excellent-computer-player.blo.

Better handling of begin/start score.

Updating watermark.

Changing framerate from 100 to 59.94, scaling frames crude 2x.

Removing some watermarks, adding the 1708x960 pixel watermark, adding a sample
BLO file.
