Display ID of hovered (or selected) Tile in Level Editor

[Epono]

With big tilesheets, it's sometimes hard to tell what is the ID of a given tile, making it a bit difficult to troubleshot tilemap creations. I think it would be a nice addition to have it displayed right under the zoomed view of the hovered tile, or maybe under the mouse coordinates in the level, on the top right.

What's your opinion?
