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.
Fix Exception (no sequence executor) when press Play after Execution Stop/Start.
Essentially we just hook the Execution state changed event and free up our context on 'Closing' (it is going to be release anyway) and recreate it when Execution returns to 'Open' state.

This change also avoids the no executor Exception on Play after SetupDisplay/Cancel.  However, something is still wrong.  The sequence looks like it is playing in the editor, but the Preview doesn't show anything. Clearly something is not getting re-connected by I don't know what.  Closing/Opening the editor returns things to normal.

Maybe you guys can find what I've missed here?

Either way, the crash is gone in both cases, so I think this is worth checking in.
Fix issue that was causing full color elements to render lower intensities than they should in the preview.

More Instrumentation - no functional change.
Added collection for the 3 phases of OutputController Update processing:
-generating OutputCommands
-Extracting commands to outputs
-Controller processing commands

Add controller name to the new generate/extract/device Instrumentation counters.  Without this some of them can get 'lost' by the Instrumentation display framework.
Switch underlying _values from Dictionary to OrderedDictionary.
This will keep the values in the order they were created instead of letting them jump around in the list.
Fix defect where Execution would re-create/register it's counters and have them not be visible.   Basically, Instrumentation ion Add now just accepts the last counter registered with a given name.
Avoid NPE if user enters bad name for elements.
Increase upper limit on UpdateInterval (so I can play Giz's new stuff).
No functional change - just a change on the upper bound on the control.
Keep serial port Open execption from propagating (which cause problems later).
Ebrady on doityourselfchristmas reported a problem cancelling out of the SSF.  When I loaded the config on my system (which doesn't have COM1, the serial port Open throws in the device Start.  This primed things to fail when the device was eventually Stopped.  Ebrady was cancelling out of SFF which reloads system config (stopping and stating all devices).  Stopping the device failed because Start never completed successfully.  This change keeps the Open exception from propagating, thus preserving the ability to Stop sussessfully - no more crash.

BTW, eventually we probably want to guard any call downs to device handlers so that the core/base classes can preserve the invariants they count on.  But this localized fix seems to move the ball forward at least in this case.

Merge Bill's fix for the AddMultiple (Squashed)

commit 5b30d57cc829860cfae58e053f36a2ff7dee9f57

    Fix last fix for empty names from AddMultiple.
    Somehow this check ended up in the wrong place - dunno how I did that.
    This puts it in the right place.
    The way it is now, AddMultiple cannot be used.
    Should merge/push ASAP.
