Update, May 9th

Hi everyone,

I just uploaded v0.1.11 (Ed-Win-2024-05-09-11-22.zip) for Windows. This build improves the undo/redo flow and implements undo for most of the features.

Implementing undo snapshotting took longer than anticipated, and still needs a lot of improvement. Initially I was snapshotting the whole project's state on each action; and with this build I'm mostly snapshotting the modified assets, unless a bigger change is done to the project. I have to rework the flow so it efficiently diffs the previous state and the new state, and make the whole experience smoother.

This build also saves the editor state in the project file and restores it on load. Some alpha blending and opacity control knobs are added to different asset types and thing types, and issues with Quad tiling are fixed.
