Auto-tiler auto-bake

[Kenoshen]

You should be able to tell the auto-tiler to auto-bake on save. This saves us from having to come up with a separate parser to parse in the special AutoTile layer type and it reduces friction to using the AutoTiler.

Tasks

• trigger the Bake command on save
• make the Baked layer invisible and un-editable and locked to the auto-tile level
• automatically delete the old baked layer and replace with new baked layer?
• BONUS: only re-bake the levels that have auto-tile changes to them to avoid unnecessary merge conflicts
• BONUS: only re-bake the entire world if the auto-tile rules change

Questions/Concerns

• One issue that I can see being a problem is that every time you click the Bake button on the AutoTile layer, the entire Baked layer is generated. This is obviously a feature and not a bug, but the problem is that if you are editing Level_1 and then you click Bake, you've now just re-Baked every other Layer_N. And the way it handles the auto-tiling is that a new seed value is generated and used to re-calculate all of the other levels. It would be really nice if Baking had the option of only re-Baking the levels that have changes or if the auto-tiling rules have changed. That way most of the work of re-Baking is focused just on the level you are working on and doesn't cause unnecessary merge conflicts.
