/*
0.67, 20.11.1999
- New rules: Sedimental (Generations), Conway--, Conway++, Conway+-1,
  Conway+-2, Fleas2, NoFleas2, Hexrule b2o, Starbursts2 (Weighted Life)

1.00, 25.02.2000
- Library of patterns for all rules.
- Description of patterns.
- Possibility to define own rules in all rule families.
- Possibility to define any board size.
- New rules family - 1D binary, with 38 rules.
- New rules family - Larger than Life, with 6 rules.
- New rules: Brain 6, Ebb&Flow II (Generations), Busy Brain (Rules tables),
  Emergence, Hex Inverse Fire, Jitters, Simple Inverse Fire, Simple Inverse,
  Simple, Starbursts (Weighted Life).
- New rules family - User DLL.
- New rules: Rug, Digital Inkblots, Hodges, GreenHast (User DLL).
- Menu View - new option "Refresh" [F5] That repaints the board.

1.01, 05.03.2000
- Patterns file names changed to be compatible with Netscape.

1.02, 19.03.2000
- Many new rules and patterns in 1D Totalistic, CyclicCA, Generations,
  Larger than Life, Neumann binary, and Weighted Life.

1.10, 26.05.2000
- Possibility to run the applet also as a Java applivation (with Java.exe).
- List of available patterns moved to an external text file.
- Favourities dialog with selected most interesting patterns.

1.20, 20.06.2000
- New option under the "Animation" menu: Rewind.
- New color palette "8 colors".
- New options in "Color" menu:
  - set the active state,
  - activate the next state (shortcut '['),
  - activate the previous state (shortcut ']').
- "Active state/states count" display in the left panel
- New rule WireWorld, with many patterns.
- New command-line parameters:
  ButtonLabel, ViewPanelControls, ViewPanelSeeding, Family, Rule, Pattern
- User rules dialog got a '?' shortcut.

1.25, 04.07.2000
- Rules definitions were extracted from the compiled applet
  and are now specified in an external text file. It's no longer
  necessary to recompile the applet just in order to add a new rule.
- New rules:
  Generations: Burst, BurstII, Circuit_Genesis, BelZhab Sediment, FlamingStarbows,
  Glisserati, Rake, Snake
  Cyclic CA: Cubism, LavaLamp, LowBrowFour
  Larger that Life: ModernArt
  Life: InverseLife, WalledCities
- New patterns (> 400) for rules: Burst, BurstII, Rake, Snake.

1.50, 04.10.2000
- New rules family "General binary"
- New rules family "Margolus neighbourhood"
