new mechanics and fixes

- During a Puzzle, do not pause the clock when EXIT pop-up appears. (It's a cheat.)
- added Title, and "chess vision training" to All play screens.
- done: Move Armadillo "Do you want a quick refresher" pop-up. (Desert 1)
- done: Move Armadillo Advice from after puzzle 4 to after puzzle 5. He will have a completely different script.
- fixed wrong counting a capture after a promotion (checks and captures mode)
- There is always the option to skip cutscenes (even on the very first start)
- done: Change angle of hint arrow on puzzles 1 and 2.
- "Ok" Button instead of "yes/no".
- Updated NPC scripts.
- Changed Shotgun effect. Instead of just becoming transparent, make the pieces disappear for a moment, and then reappear transparent.
- done: Allow repeat of previous puzzle, unless you entered a town.
