Release 1.1 - Bugfixes and improvements.

In this release of Harder Sprouted, likely the final version, I have fixed some bugs and improved aspects of the game that needed polishing and balancing. Most notably, some guardians on special depths now properly scale with hero level rather than depth, Zot has been buffed, and crashes with the Dragon's Cave have been fixed. Avalanche is also no longer capable of doing negative damage.
