1. If there are no installed print services or NFC payment services,
we would like to allow the user to search for one in Play. However,
Play is Google specific and we should not have hard coded URI that
rely on it in settings. Declare secure settings for each of these
URI and check at runtime if the URI is non-empty, then show the
add menu item.

Added a list of active print jobs to the main print settings
screen. Selecting a print job from there leads to a print job
settings screen with more information about the print job and
actions to change the prit job state such as cancel and restart.
