Re commit Alternating Effect
Merge Gizmo's Alternate Effect: remote-tracking branch 'remotes/gizmohd/master'
Fix up the Alternating effect output directories, and add it to the solution.
Remove the Modules/Intent directory. Not sure why that stuff is there; it appears to be in the Vixen.Sys module...?
Remove the Grayscale output filter; it's not used and didn't build.
Code formatting cleanup for the Alternating effect (and editor). No functional changes.
Merge Derek's cleanup changes. NOTE: prior to the formatting changes, so the merge was messy. Might need to review to ensure nothing fell through the cracks.  remote-tracking branch 'remotes/derekbackus/master'

Conflicts:
	Application/VixenApplication/ConfigElements.cs
	Modules/Effect/Nutcracker/FastPixel.cs
	Modules/Effect/Nutcracker/NutcrackerEffects.cs
	Modules/Preview/VixenPreview/VixenPreviewControl.cs
	Modules/Preview/VixenPreview/VixenPreviewModuleInstance.cs
Code formatting changes after recent merges. No changes of any substance.
Fix up discrete color operation for the Chase, Spin, and Twinkle effects.

Implementation is a bit iffy -- lots of reused code :-( -- but it'll do for now.
Fix to light last pixel in Nutcracker Effects
Some error checking on Nutcracker effects
Elements now redraw when a row is resized.
Fix Nutcracker dropped on a single element crash
Added NodesChanged event to the preview in preparation for the future
Fixups for the alternating effect to support discrete colors, and sane default values when applied to discrete elements. Still needs rendering fixed up (changing to using Pulse and/or SetLevel effects).
