Support of saving/freezing selected dice

[Ben-Kaniobi]

It would be useful to select particular dice, which then remain on the same face for the next rolls until they are unselected again.

This would make it easier to play games like Yahtzee (with 5 dice), or Silch (with 6 dice) and probably many more.

This could also be extended so that the saved dice can be manually re-ordered and the number of points is displayed automatically.

UI idea:

• freeze by pressing long on dice to keep
• change the rendering of frozen dices (ex: different color)
