Migrate to GStreamer 1.0

- As per issue #308 I am going to migrate the code over to GStreamer 1.0

- This branch will incrementally help move the program over to GStreamer 1.0 but currently the Windows port of PyGo is incomplete, as well as the included GStreamer 1.0.5 implementation is missing 2 key video sinks.

- If successful this port will work on Linux but will not work under Windows
