Allow placing items against some blocks

Browse Source 
We define a tag which allows specifying which blocks can be used. Right
now this is is just cauldrons and hives, as they have "placing into"
semantics.

Closes #1305. Many thanks to Lindsay-Needs-Sleep for their initial work
on this!

Fixes #1008. I believe also fixes #854.
