BlastFX 1.2.2 Released

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.  Unfortunately I haven't had time to implement some of the other ideas I had for BlastFX, but maybe they'll appear in the future.
