Request to enable/disable building of a ghost

[taori]

After building bigger in factorio i ran into the need of having better methods of planning a factories design without actually building it and have bots deliver everything, but once the map is covered with roboports this is annoying to accomplish. With 2.x a lot of labs mods broke so i looked into alternative mods and ran into the mod i did not even know i was looking for all the time - https://mods.factorio.com/mod/Construct ... rContinued

As far as i can tell the mod accomplishes its functionality by instead of creating ordinary ghosts, creating ghosts in the context of another faction, which however introduces several issues and bugs that are quite likely hard to fix such as:

- unapproved ghosts are not visible, unless they are in your vision
- building belts does not auto add underground belts
- direction of underground belts cannot properly be controlled
- and a couple others as visible on the github page

All of these issues would be easily resolved if the modding API contained the following:
- player.buildGhosts true/false
- ghost.allowBuild true/false
- robots must only build buildings, which have allowBuild set to true.

With all those 3 bits given the mod could be completely changed in how it accomplishes its functionality and work perfectly fine.

By changing the game that way, that mod could have pretty much every issue it has fixed in a heartbeat.
