Changelog v1.7.1 - Level Editor Bug Fixes

Bug fixes:

• Fixed issue where the game was trying to inappropriately access the foreground tiles list (which is structured different than the objects, backgrounds, and background tiles lists), causing the game to crash when navigating the foreground tiles sidebar via keyboard/controller.
• Fixed issue where not all the foreground tiles for Mushroom Mantle, Metal Mines, and Secret Shadowsphere were showing.
