This makes loading faster, with less I/O, avoids unnecessary
code duplication (around 1k lines shaved), and ensures that
all the panels link and work appropriately.
By the same token, it will stop external panels from being
created, and loaded.

PpNewPrinter contains asynchronous method for installation of
new printer. The new printer is specified by given parameters (e.g. name,
device-id, device-uri, ppd-name, info, location, ...). (#683229)
This commit adds PpHost object which represents a remote
host from which we want to get printers. It contains
asynchronous method for enumerating printers list from the host
using CUPS' SNMP backend and method for enumerating printers list
directly from the remote CUPS server running on the host. (#683229)
PpCups object represents local CUPS server. It contains
asynchronous method for getting printers installed on
the server. It is an asynchronous version of cupsGetDests().
(#683229)
This commit places list of jobs to separate dialog. The dialog
is updated through calling of pp_jobs_dialog_update()
from "Printers" panel because the panel is already subscribed
to cups notifications.
Add Options dialog which allows users to set more options than current dialog.
The dialog reads printer's PPD file and add its options to the dialog together
with some preselected IPP options (#678637).
All operations in the dialog are asynchronous.
During implementation of this, the option for setting allowed users was removed
because this is not suitable for this panel (the option is intended for
administrators).
This commit adds popup window which when activated allows
user to select PPD from local database of installed PPDs,
select directly PPD from filesystem or select one from 3
recommended PPDs (#678637).
The popup is activated by clicking on model field (the panel
has to be unlocked). It starts to search for the best PPDs
available immediately after its popup.
All operations are asynchronous.
The dialog is able to add printers discovered by cupsGetDevices().
It can also add printers from a remote CUPS server by typing
its address and selecting printer we want to add (#640734).
