Add some usability features to the TilesetBuilder

- title bar shows tile position (x, y and tile nr (from left top))
 - make 'overlays' button a toggle button and properly sync state with
   tileset surface
 - add export option for 'Template CellID <-> tile number' mapping
 - overlay pen color is now white (todo: make configurable)
