Removing a println().

Making level 28 a tad easier.

Changing some of the Tetris speeds etc.

In TetrisBoard not using outlineCoveredHolesOnClearedLayersEvents.

Fixing an HTML formatting/misspelling error in Javadoc, in WellColors.

Adding class TetrisConstantOverrides.

Adding class TetrisWellColors.

A first stab at override() in BlockoutConstants. Not tested.

In BlockoutConstants, changing each of the 'public final static' member
variables into a function, simply by putting '()' after the member name and
then adding a 'return' statement. This is an incremental step towards getting
BlockoutConstants to be more configurable. In particular I want to override
some of these for Tetris.

In SimpleGameLogic, adding a new member variable
'm_newBlockPositioningStrategy', and exposing its configurability through one
of the constructors, thereby making a reverse incompatible change. I didn't
want to introduce a third constructor. BlockoutConstants also now exposes
'newBlockPositioningStrategy'.
