Fully explorable buildings

[snegec]

Cottages/buoldings in all three maps often have doors to either pantries or basements inside the house we can't open as of yet.

There's also some basement entrances that are obviously not blocked, but can't be entered - example: burned out houses in coastal map have a basement.

The only basement we can currently enter are:

1) Bunker

2) Basement of the large Barn in Unpleasant Valley
