- Level Editor (beginnings)
   - press F4 from main menu to start editing level 2
   - supports panning view by moving mouse while pressing the middle mouse button
   - supports deleting blocks by point and left mouse click

- Map changes
    - altered tileheights in tilesets to be 128 instead of 64 for Ground, Solid, Breaking Ground, Ice, and Mud blocks, so the image applied includes the sides
    - essentially this means that the sides for these entities no longer need to exist, so they are destroyed on load
    - the plan is that level data should not need to contain any information about the sides in the future, so nothing will need to be destroyed on load
