Visually separate directory background from sidebar.
Lower shadows so the "real" effect isn't so prominent.
Hitchhikders:
Consolidate bool values in config.xml files (were in dimens.xml).
Add missing supportsRecents & supportsSearch methods
to RootInfo.
Rename RecentLoader to RecentsLoader so it doesn't defy
searching for "Recents" string.
Move Downloads below the divider.

Initial Material asset drop, which still needs some tweaking. Moved
back to framework list item selectors, giving us ripples. Using
accent color overlay for activated items. Align all items to new
Material grid, including insetting list divider and resizing list
items on wide screens.
Fix obscure RTL drawing bug.
Still lots of work left.
