GTK3: port libunique ->GtkApplication as build time option

Add --disable-libunique configuration option for GTK3 builds. This builds a port from libunique to GtkApplication. keep GTK2 builds unchanged

Caja can now be build with GTK2 and libunique, GTK3 and libunique, or GTK3 without libunique using GtkApplication instead

GtkApplication port  Based on cherrypicked nautilus commits from
https://github.com/GNOME/nautilus/commit/a8481ee4bd8d34e792d63598fa5efb47736f9de4
main: adapt to GtkApplication changes
through
https://github.com/GNOME/nautilus/commit/c3382e0415d51082545f277c380d37be160e8d2d
application: move nautilus_application_new() to its own function

GTK3/GtkApplication builds:  add --force-desktop option
This is useful for other DE's

All: StartupNotify=false in .desktop files, as caja never connects to notification daemons and in GtkApplication builds this causes busy spinning curors
