Start a new development version 0.4.11
Make walls lit
Add oriels

They are windows into outer space, so toally black and so invisible
unless the frames are directly lit (unlike other walls that always
reflect some ambiet light).
Rename dark/lit++Legend to legend++Lit/Dark
Refactor TileKind content
Don't use any dark paths

We don't have colours for them, anyway (ideally we need 2 colours
per feature and separate 2 for its dark variant, and for paths
we only have 2 total, 3 if we use yellow for currently seen dark tile,
just as in case of normal floor).
