Commit 157d413d42b12d98acf053f50f762caf5830ae69

Store the tileset image width/height in the map file

Useful for when you can't load the image just at the moment, but still
want to figure out where your tiles should be.

In the future it can also be used to be able to load maps correctly
after extending the width of a tileset image, which at the moment messes
up the tile indices.
