Unity Security Update

Recently, Unity got in touch  with developers to let us know an older version of the editor has a Security vulnerability that was passed into all projects made prior to the newer editors.

I'm not 100% sure if it affects Collared, but to be safe  I've rebuilt it using the newest version of Unity. Please download the new version, and delete any old versions you may have on your computer.

This version *should* be functionally identical, though you might lose your savegame, and need to start over. If you hit any bugs or crashes, let me know. I didn't do anything to it, except Update to the new Unity editor, so there might be some unexpected issues with compatibility there.
