The Common Print Dialog Backends (CPDB) concept has GUI-toolkit-independent backends for each print technology (CUPS, Print to File, cloud printing services, ...) and each print dialog (GTK, Qt, Chromium, ...) is supposed to use this backend, so that changes in print technologies can be centrally and quickly covered by changing the backends and everything new gets available in all print dialogs. This commit provides a GTK print dialog backend to add support for the CPDB concept. It communicates with all installed CPDB backends and so gives support for all these print technologies to the GTK print dialog. To make use of CPDB the GTK print dialog is supposed to be installed with this backend and the 'Print To File' backend, and not any others to prevent printer duplication.
