grafx - Extensible Java Graphics Package Code

Adding TetrisInputTranslator and TetrisModeAction, but there is a problem with
inversions. Difficult to explain but a point inversion/reflection isn't what
we want.

Now using BlockModifier in TetrisTest. It is working.

Adding 'checkBlockExtents' to Level and to NightmareModeLevel.

Modifying NightmareModeAction constructor which now accepts BlockModifier
object which may be null.

Adding BlockModifier.

Adding LaunchTetrisTest and TetrisTest. While these do compile and don't
break the build, they are far from finished and most definitely won't work as
intended at this point.

In BlockGenerator, changing rotateX(Block) from 'private' to 'public' access,
for Tetris.

Resurrecting TetrisConstantOverrides and TetrisWellColors.

I had some modern ideas for this stinky, sucky game known as "Tetris". The
game has gone to shit because non-engineers who lust after the green printed
toilet paper which we know today as "money" (i.e. Henk Rogers) try to think
of ways to "maximize their return on invetment" by writing rule books about
Tetris game physics, their so-called rule books being totally flawed. Well
Henk. I'll tell you what. The best way to get your return on investment is to
polish those shoes belonging to the tribe of people who print your "money"
supply. You can start with the members of the Rothschild family for example.
When you're through polishing their shoes I suggest using that green paper to
wipe your stinkin' ass.

Changing version, 2.3.1 --> 2.3.2, in webpage.
