Subject: Bug 694025 - GLib drop support for adding interfaces after class_init
Without this Dia crashes at startup with new GLib version and the
DiaGdkRenderer being default. Make a new DiaGdkInteractiveRenderer which
follows the pattern also used for DiaCairoInteraciveRenderer. This should
be functional equivalent to what was there before and should work for all
current GLib versions.
