SystemUI: Allow themeing of the "no recents" label

This commit defines the label of the "no recent apps" label as a
simple color which allows it to be modified in themes.

Framework: Make the dialog divider color themeable

The holo blue color might not be suitable for some themes. This commit
swaps out the background of all titleDivider elements to use another
resource. This has no difference from the perspective of the user of a
"stock" build but this is huge for theme users.

Thanks to Arz Bhatia for the suggestion.
