dependency from TV and stereo (uses in-built silicon lumps if Mesecons isn't
present). Replaced speakers' Mesecons Noteblocks with copper ingots from
Moreores.
The textures were drawn to counteract this, without my realizing I was doing
just that. :-) Fixed. Also replaced all "tile_images" references with "tiles",
since the former is deprecated in favor of the latter.
