Goal of this commit is to not overwhelm UI when a lot of printers is added
to CUPS. You can reproduce this situation when you add e.g. 30 printers using
lpadmin. Th UI stops to respond for some time.
To do so, the printer entries are not deleted every time there is a request
for updating of the list of printers but only new printer entries are added
and printer entries of deleted printers are removed. Other printer
entries are just updated by new method pp_printer_entry_update().
Which, by the way, is almost whole taken from pp_printer_entry_new().
This needed to add sort function for the list of printer entries. It sorts
printers according to their names not taking case into account.
In the similar manner, the filter function was extended to not show printers
which are being deleted. This needs a list of names of deleted printers
which we keep until they are really deleted.
One important thing here is the "reference" object which points to the panel
itself via its "self" key. We pass this object to the pp_printer_delete_async()'s
callback so it knows whether it can remove the printer's name from the list
of deleted printers (once the panel is being destroyed it clears the key itself).
Add action "show-jobs" to printers panel which
gets printer name as a parameter and shows user
jobs dialog.
Syntax for trigerring this action looks like:
"gnome-control-center printers show-jobs my-local-printer".

This commit adds method for triggerring of authentication of print jobs
to PpPrinterEntry. This is needed for asking for authentication of jobs
of a printer from the main panel.

The previous implementation of the panel was unable to individually
update a PpPrinterEntry jobs count and its PpJobsDialog.
These changes make the job notifications trigger updates in the
PpPrinterEntry UIs, keeping track of job events on the go.

This commit introduces the following regressions:
- no possibility of renaming properties such as printer names,
location, or changing model/driver. This issue is going to be
solved nextly by the introduction of the PpDetailsDialog.
