1.01.09: Topaz and Iolite Gem Areas

Added both Topaz and Iolite Gem Areas into the layers of the Mylantis Caves. You are shrunk deep into these sponges and must enlarge out of them to get treasure.

To increase performance, we changed the algorithm to load chunks. Previously, only procedural world generation was done by separate threads. Now, both that and the process of reading a chunk file (a file that stores chunk changes) is done in a separate thread.

Added trophies for several areas including Denver, which is an area where there is a forest next to a desert.
