New lands, and other improvements

HyperRogue is updated again (v5.0)! It includes two extra lands:

• The frozen lake of Cocytus is now reachable after collecting 10 Demon Daisies. This land was previously available only for cheaters (and extremely good players), but the new version is better.

• The Dry Forest, full of trees and creatures who would do everything to stop you, is now reachable at the same time as R'Lyeh.

Despite adding new lands, it is still sufficient to get treasures in 9 lands to reach Hell. Collecting Hyperstones requires mastering all lands, and also it has been rebalanced, so new 5.0 leaderboards have been created for Hyperstone-related scores.

This version also includes numerous minor bugfixes, gameplay and user interface enhancements. It also includes support for multiple languages (Polish is ready, German and Turkish should come soon -- please contact me at zeno@attnam.com if you want to translate HyperRogue to another language).

Don't get burned by Fire Fairies, don't drown in Cocytus, and have fun!
