[1.0] Allow mass un/forbidding of construction ghosts

[Ambaire]

The new un/forbid tool is a nice addition. Would it be possible to let it affect construction ghosts as well? I like doing extensive planning of my starting base before beginning construction, and it's a bit painful to manually forbid every single ghost that I don't want constructed yet. I know about doubleclick to select a group but it's still limited and indiscriminate.

pan your camera to include only things that you want forbidden, double click the ghosts and press f.
rinse and repeat.
yeah it isn't ideal but thats the fastest way I can do it.
