We used to show a single notificaiton for every print job but
this is against th UX guidelines. Since we have to lead by
example, this change adds coalescing of multiple notifications.

Added a list of active print jobs to the main print settings

settings screen with more information about the print job and
actions to change the prit job state such as cancel and restart.
