Note: I took out the unnecessary nsContentUtils include file locally -- we can't link to that stuff anyways.

r=me

1) we could want a common way to know if element is dragable
2) we could think of how to deal with dragged selection
3) we could expose dropeffect extracted from dataTransfer object of dragEvent on dragover

but it's target of further investigations

and please line up

nsAccUtils::SetAccAttr(aAttributes, nsAccessibilityAtoms::draggable,
1863	        NS_LITERAL_STRING("true"));

properly if it isn't.
