Another small update:
- Moved from Godot Engine 3.0 to 3.1, this might fix some crash issues for some people (maybe)
- Fixed some shader issues from switching over to 3.1
- Fixed an issue with loading GPL colour palette files, the values were being read in incorrectly
- PAL palette saving was also broken in some cases, but this should be fixed now
- Render settings are now saved with each project, yay!
- There's probably some other stuff I forgot about... but it would be minor things anyway.
