Gutting the OverviewMap control to give it an update. Now uses a click handler and a drag handler instead of its own event handling code. In addition, the control now has a minRecSize property. When the extent rectangle is smaller than the specified size, its style is switched. By default, we provide a rectangle replacement graphic. This can be customized with CSS. Finally, I'm tucking in one non-API property. The dragging arg sent to map.setCenter is now stored at map.dragging. This gives easy reference to dragging state where a reference to the navigation control and its drag handler is not convenient. r=pspencer (closes #1244)
