Title: Fixes for shift selecting/unselecting groups

Shift selecting/deselecting no longer causes the group to have its
transform re-applied.

You can no longer drag a shift added object separately from the group.
This also fixes the issue of the object jumping on addition to a group.

Objects in a group are now rendered to the upper-canvas in the order
they are in on the lower canvas.
