gst-editor updated for Gtk+ 3, GStreamer 1.0 support in progress

[Robin Haberkorn]

Hello again,

the project is now in a state where it compiles and runs against
GStreamer 1.0. It survived some basic testing but is far from being
bug-free.

Loading and saving pipelines is currently disabled. I will work on that
as soon as I have evaluated a few more technical aspects.

Best regards,
Robin
