Added animated symbolic dice button

[cholmcc]

This adds the possibility to add one or more animated dice to a module. The dice are animated using the defined images with configurable number of frame and frames per second.

One class AnimatedDiceButton has been added, as well as some translatable strings, and the documentation has been updated.

Dice like these can be added by Add Symbolic Dice (animated) in the module context menu.

Closes #14306

Animated symbolic dice in VASSAL

Here is a component that allows one to make animated symbolic dice in VASSAL. It extends the functionality of SpecialDiceButton to allow for animation of the dice.

The animation is done by picking, at random, some number of other die faces than the result, rotating these faces at random, and then showing each image in turn until the last image which is the result of the die roll.

Looks neat! Is it possible to add a sound to the animation, so I can make it sound like rolling dice?

Yes, you can. As this component inherits everything from Symbolic Dice Button, it also inherits the configurations

• Play a sound
• Sound Clip

Ideally, the animation would in that case be as long as the sound clip, or vice versa. For now, make sure that the product of the configurations

• Number of animation steps before result (steps)
• Frames per second (FPS)
  is roughly the same duration as your sound clip. That is, if your sound clips is duration long in seconds, then aim for

duraction = FPS * steps
