Update to latest 42.6.0

Merge latest master.
Observed lots of sink-related code additions from the devs, along the lines of what users reported issues with.

42.2.0 update incorporation of vanilla changes.
Devs added the same patch I added to allow stuff to be placed in front of doors, resolved merge conflict.
Some other apparent bug fixes from the devs.

Allow objects to be placed in front of doors.
Comment in code does not cite any bug-related issues with doing this, and basic testing of placement and pickup seems fine.

Initial support for B42

Fix missing code to bypass items like "sinks" that have no required skill but have a break-chance.

Added Military Crate to whitelist.

Rebased to latest version of code. Required manual line-by-line patching. Tested with a variety of pickups and appeared still functional. Higher chance of bugs than usual.

Revise whitelisting to allow all shelves except single and double wall attached shelves (specified manually by name).

Updated for v 41.73 release.

Reapplied code changes to latest version of the lua file. Missing code block related to inventories, likely causing some bugs.
