grafx - Extensible Java Graphics Package Code

In SimpleGameLogic, no longer using Cronos. Cronos is useful for doing video
recordings. There is no reason for it to be used in SimpleGameLogic, so far as
I can see; in fact it may only open up possibility for cheats.

More work on VIDEO-RECORDER.txt.

Adding beginnings of VIDEO-RECORDER.txt.

Making some minor code improvements when pausing for a certain time. These
section of code are quite intricate and tricky to get absolutely perfect.

Streamlining a bit by cutting out one call to Cronos.currentTimeMillis().

Showing how to use Cronos.Override. In SimpleGameLogic.

Move from System.currentTimeMillis() to Cronos.currentTimeMillis() in
LocalBlockoutBoard.

Forgot to call s_override.wait().

A first pass at Cronos.

Filling out the logic in Cronos. Next, I want to figure out how the enact a
change in the timekeeping. I don't want to pass objects around. I know it's
"unsafe" practice, but I want to be able to adjust this globally w/o passing
around any instance.
