[1.1.4] Inconsistency - replace with ghosts

[burninghey]

With 1.1 the game is teaching me, how easy it is to replace belts with ghosts. But I'm missing the same functionality for:

- replace belts with more than 1 piece at the same time

- replacing walls with gates

- place an assembling machine with modules over one without

- upgrade assembling machines to another tier
