Long Requested Bugfix Update

Version 1.7 Update

• Fixed desync issues with the durations of powerups, resulting in confusion and potential illegal game moves.
  • To fix the powerup desync issue, all powerups are now based on the amount of turns passed since the player picked up the item that gave the powerup, not when the powerup item server message is received.
• Check/checkmate calculations now take into account the "Extended Movement But Eventual Death" powerup.
  • This was quite the troublesome bug to track down, but I found the one faulty conditional statement in the code and fixed it.
• Stalemates are now taken into account in the loss condition checker.
  • While items usually can mitigate stalemates, where one player cannot move any pieces at all, this new update counts the rare cases on which that happens as a loss for the stalemated player.

Please feel free to let me know of any bugs you encounter so I can make Chess But Better even better!
