Expand blacklisting items to all map item placing

Things such as turrets firing weapons and taking down furniture could
place items on that map that were blacklisted. Make sure an item is not
blacklisted before placing it.

There is some minor possibility for crashing here, by adding a new way
this function can return a null item reference. There were already ways
this function could return a null item reference, so anything where this
would cause a crash could already be problematic.
