v1.2

- Added a starburst effect on top of the flares.
- Added a distortion quality setting to the lens flare.
- Added a flare blur setting to the lens flare. This doesn't actually blur the effect, but rather selects a different lod of the screen texture, which means that the flare bias should be reduced when this increases.
- Changed the camera controls in the demo to the WASD keys.
- Updated to Godot 3.1.1 where the screen texture is not clamped at brightness 1.
