Version 3.2.1

This update makes some small bug fixes and adjustments regarding how maps are saved and how sprites are rendered.

• Fixed bug where multi-textured tiles are assigned the wrong textures after saving sometimes.
• Entities with non square sprites will now be scaled vertically to maintain aspect ratio.
• Fixed issue where missing textures are overwritten with other textures after saving and reloading.
• Removed Total Editor 2 importer. This feature is only really useful to myself and I found a better method for converting these maps.
