BHV-737: Reset header marquee after closing accordion. Stop header marquee when opening pickers.
BHV-737: Remove start/resetMarquee altogether, since focus change handlers in marquee provide the correct behavior.  Also prevent enyo.Drawer used in expandable list items from resizing the container (which also resizes itself, causing the marquee resize handler to start the marquee hold/restart process).  Only perform marquee reset in inputModeChanged if mode is changing after generation; otherwise it's redundant (and happens before marquee create runs).
