Support for custom importers for .world files?

[ninjuit]

I saw that .world support got added here: https://github.com/Seanba/SuperTiled2Unity/issues/162

I was wondering if there were plans to add support for custom importer extensions similar to what you have for .tmx files.

Right now I'm using custom importers to generate some prefabs based on each tmx file. I'd like to be able to tell those prefabs what world they are associated with, but there's no support for extending the .world importer! I figured I would, during the world import, find the prefab I made for each tmx file and update it with info from the world files in the project, but I didn't see a simple way to do that w/o editing the importer directly.

I think this would be a really valuable extension for people making use of Tiled Worlds!
