Isle of Puzzles Update

The game got much more attention than I expected! I'm glad to see it clicked for a lot of you.
Massive thanks to @bartbonte for the plug on their blog.

This update has a couple of fixes and most importantly it introduces a "flagging" mechanic: Right click a tile to remind yourself that it can't have a building on it.
Hope you like the improvement and let me know if you any feedback.
