WorldSim v0.0.036-dev

Small release prior to work on load/save functionality.
Tile query info has been moved into its own panel to prevent spamming the in-game console.
Texture view is set as default view.
Up to three local maps may be active at once. (Right-click a tile to activate it).
Local maps have been reduced to 64*64 tiles for easier testing.
Game now has a background image on the main menu.
Subterranean view option has been added. Currently completely useless.
