Multi-select move requires holding control/shift

[wilsonpenn]

The old behavior used to be that if you selected a group of items, you could then click and move that group. Now the behavior seems you have to hold control/shift to move a group. If you click+hold on a selected group, it will re-select just the item the mouse is on rather than selecting the group.

I personally prefer the previous behavior, but the current behavior is also okay (though I think less intuitive since it doesn't match what most major OSes do in terms of UI controls for multiple files).

Joe's comment on discord:

"It has to do with how everything updates everything. The level editor sends an update and it sends it back... So the item selector on the right got changes which probably fucked up that by some annoying propagation issue. Like now it will show the items selected properly, but if it gets updated and you are not holding shift it will reset it :/
Should be easy to fix. So just create an issue and I'll probably get around to it."
