Suggestion regarding group selection & assignment

[Iklash222]

When you got air assigned to group including plants.
(ie each produced get into group)

Fix so it can allow targeting. Now one has to ctrl click all airstrips to be rid of them in "selection" to be able to do so.

OTA didn't have that limitation... Ie plants could stay they would just not be selected when you select group.

->Do like if you shift click group then it will target only the factories.
