Quicksettings: Fix theming of basic tiles in edit mode

In edit mode the background of basic tiles was
overridden (not sure why), which broke theming.

We'll just remove this...

Themes: Full support for AOSP Volume Panel

- Recreate VolumePanel with theme enegine UiContext.
- Revert this https://gerrit.paranoidandroid.co/#/c/4375/ since we don't have
  the code with the panel they refer to. Just leave UiContext commented out, maybe
  we'll need that lately.

Themes: Full support for PA GlobalActions dialogs + ancient derp fix

- Use Theme Engine UiContext for creating dialogs.
- Add theming to reboot confirm dialog(s), send UiContext to ShutdownThread aswell.
- Fix dialog not being recreated when calling showDialog() and dialog being not null is nullified
  without being recreated (we don't call handleShow() there).
  Introduced here https://gerrit.paranoidandroid.co/#/c/128/ but not affecting the final result,
  now we have Theme Engine tho we need it.
