v1.1 Bug-fixes and pause menu

Quick patch adding a pause menu, and fixing two crashes! Changelog:

• Added pause menu where you can set the pixel size, toggle fullscreen, toggle vsync, and restart or quit the game
• Fixed a crash when holding a stack of driftwood over a treasure chest containing more driftwood
• Fixed a crash when releasing a cannonball that was already supplied to a ship once
• You'll now keep the steel ship when you wash up or die
• Scimitar won't break anymore
• Different transitions for washing up and dying (to make the difference more clear)
• Throwing barrels at skeletons now actually does damage
• Kraken now has less hitpoints!

Thanks to the people who reported their crashes/bugs! Enjoy.
