Unfortunately, easymesh code still relies heavily on its specifics, so I’m
letting it live as lol::easy_array for the near future. But it’s going away.

Most input and GUI files are now in a common ui/ directory. The platform/
directory is no longer, as everythyng was moved to application/ or ui/.

This was not a very smart class. We replace it with a bidirectional map.

Added Texture (by image) update in TextureImage (and tileset)
Added lolimgui first integration pass

First pass on EzMesh integration (doesn't work yet)

and 2) fuck the Visual Studio compiler that crashes when confused.
