DialogFragement: Add null pointer check for mDialog for protection

DialogFragement can be dissmissed just after the Dialog is
established. This will cause NullPointerException.

SystemUI: Make percentage appear for hidden batt

This commit makes the battery percentage appear in QS when the user
chooses the "hidden battery" option as the battery style. Prior to
this commit, the same battery style was used for the QS tile just
without the percentage indicator. This means no major changes are
being introduced but the usability is being improved as the user
can glance at the QS tile to see the exact percentage instead of
being forced to open the linked Settings page.

Fixes AOSPA-687.

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.

IconPackHelper: Don't respect an icons original size if too large.

  - Otherwise, if an application isn't following app icon guidelines,
  it can create an OOM situation when creating the new icon based
  on the original resource's height and width.

SystemUI: Correct settings observer usage

Settings observer was already created by a global variable, but
it was never used and instead a new one was created in start().

Corrected the code to utilize the already created settings observer.

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.

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.

SystemUI: Separate system bar BGs for themes

This commit separates the navigation bar background colors from the
status bar background colors which allows more modular theme-ability.
Backwards compatibility for the old system bar values is still
preserved, but the new values are to be prioritized.

Thanks to Arz Bhatia for the suggestion.

For initial change ID Ibe579d16ea35ca5bdcfe9f98143c3f91cd24900f

This commit removes some hardcoded values and cleans up special casing
as suggested by people in CM. This shouldn't really change anything
for the end user or the theme creator. This only makes the codebase
easier to maintain and understand later down the line.
