grafx - Extensible Java Graphics Package Code

Changing DEFAULT_VID_FPS from 50 to 60. This seems to synch up better with
typical refresh rates. I don't know about Europe.

Adding file 'excellent-complex.blo'.

Adding file 'excellent-simple.blo'.

Removing all BLO files from data/ dir.

Upping the number of layers to clear on level 26, by one layer.

Moving code around in BlockoutConstants to make it easier to modify quickly.

Adding a new level 21, pushing levels 22 through 29 to now be levels 23 through
30. Level 21 is a 4x3 pit with reasonable blocks, good for demo.

In LevelTest and in NightmareLevelTest, now using external class StatsUpdater
instead of relying on duplicated code.

In LaunchNightmareLevelTest, the introductory audio (as part of
DaemonAudioAndAWT.createAudioAndAWTThreadsAsDaemon()) has been changed from
"woohoo.au" to "speedup.au" to be in line with other start/spash screens. The
"woohoo.au" is very loud, and isn't suitable as an introduction.

Removing fully qualified constructor with statement
'new net.blockout.event.encode.SynchronizedModeGameRecorder()' (removing
package name because that class is being imported).
