Windows should be copy-from'd from the basic window type

[Coolthulhu]

Windows have a lot of copypasted data.
It's now possible to use copy-from for most of the terrain data, including bash data.

I have changed some of the window types, which were previously hardcoded in map::shoot, when jsonizing map::shoot effects.
I skipped the rest, because there are just so many window types in there:

• Single/double/triple glazed windows
• Standard, taped, boarded, reinforced
• With curtains and without
• Multiple combos of the above

Using copy-from would not only increase the "contrast" between window types by showing which flags are added or deleted.
It would also copy the new map::shoot data around, letting the weird window types react to ranged attacks properly: by not stopping a .50 BGM shot just because they are non-transparent (taped, boarded or curtains drawn) and non-passable.

Alternative (to manual) solutions:

• Wait for someone (me?) to implement multi-copy-from, allowing abstract "templates" to be combined into one concrete type, then using something like:

"copy-from": [ "window_abstract", "window_domestic", "window_curtained", "window_barred" ]

• Write automatic tools to determine what to copy-from and how to extend and delete from it, then apply it to windows
