Add a new edit mode to Automation Editor

	Adds another editing mode to Automation Editor (DRAW_OUTVALUES), specific to deal with node outValues. The Pixmap being used is the same as the DRAW edit mode for now.

	The way it works now:

DRAW Mode (Shortcut SHIFT+D)
	Shift + Left click = Draws lines of nodes
	Left click = Draws/Drag node
	Right click = Remove nodes

ERASE Mode (Shortcut SHIFT+E)
	Left click = Remove nodes
	Right click = Reset outValues

DRAW_OUTVALUES Mode (Shortcut SHIFT+C)
	Left click = Drags outValue
	Right click = Reset outValues

	Now using a switch statement on the events to make things more organized.
