Would it be possible to support ghosts?

a) ghost inserters
b) inserters from/into ghost buildings

I really like this mod, but adding inserters to existing buildings often means that the inserter grabs at least one wrong item before configuring the filter. I don't want to resort to other means, such as using parametrized blueprints to build filtered inserters.

Won't be trivial, but it's an important upgrade. Ghosts in 2.0 caused a lot of pain and crashes for the mod in the past, so hopefully it won't be too difficult to add.

Should be working now
