#4 Playing issues

[msdobrescu]

Any kind of game choosing, the following problems occur:
- the white ball is moved when it end up near to a hole, between the hole borders, without falling into the pocket. I don't care if the next player has difficulty because of limitation of the shot, I think it is more realistic to let the white ball where it stops, makes the game funnier.
- sometimes the balls remain in infinite rotation or slowly/fast fly off the table

[Sambodhi]

Balls rotate infinitely only when the axis of rotation is exactly perpendicular to table.
