Dynamic Update

Changes:
- Plugins now have their own preview.
- Gravity, CMD and Maze mini-games now are more difficult, dynamic and engaging;
- Dialog system now has been changed - dialogs no longer disappear after a set duration of time, now the player has to skip them manually, using space bar.
- Hints no longer disappear after a set duration of time - now they stay on screen until dialog ends.
- If bordering horizontal tile in Maze is blocked, the game starts with the player moving downwards.
Fixes:
- We managed to fix a bug, which prevented coins from being given to the player.
- BattleHack and Мatrix no longer freeze.
