Change player assignment of multiple simultaneously selected objects

[Erik Johansson]

It would be nice to have the ability to change ownership of multiple selected units/buildings at the same time, currently only the first selected objects ownership is changed.

See #1213 for the multiple selection rotation :)

The problem (as I see it) is that Atlas' current logic for multiple selections doesn't really handle this possibility, so it likely needs to be redesigned. I agree we should add these features though, along with forest/entity/delete brushes, as they would make a big difference for usability.

Ah, I thought I had seen that before (but apparently I was too lazy/tired to search for it :P ). Thank you, I'll update this ticket to only mention the player assignment :)

Don ´t remember since when but this is fixed. This is particularly useful for trees.
