Themes: Add helper methods for creating complete component maps

These methods can be used to apply a theme while replacing any
components not found in the theme with the defaults.

Default components come from the default theme for the system
with any missing components in that default theme coming from HOLO.

SystemUI: Allow theming 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. This resource
matches what CM has been using in cm_colors.xml for a while.
