Setup: Added the ability to 'reverse' the selected controller outputs in the simple patching (to make it easy to patch opposite ordered stuff).  Eventually this might go to a new patching form, as it's starting to get a bit complex.
Setup: fix bug when rerunning color setup helper and reconfiguring existing filters (doesn't reference them properly).
Improved the error message in the grid element drawing error handling.
Fix Exception on Cancel from CreateGroup from selection.
Also avoid firing OnElementsChanged on Cancels in a few other places.
Fix Stack Overflow when re-grouping.
Create ElementTree::GroupFromSelectedNodes was adding the new group to itself as a child because the AddSingleNodeWithPrompt changed the selected item in the element tree.  This fix simply saves/uses the original selection as the children to put under the new group.
