Update 1.3

Improvements

Further optimizations for lighting (lightmap baking) and lower render quality

To do

Initial load time is still much longer than I want. First render of new assets (like enemies when they spawn) still causes stuttering.
I'm looking into ways of improving this. Preloading doesn't seem to help. I suspect Godot does some hidden optimization any only loads scenes when they enter screenspace. Not sure how this could be disabled.
