Added readme file to keep github happy
Added a minimal test bed script to experiment with needed changes for gstreamer 1.0 and pygi
Gobject conversion. Changes in way we handle magnitudes due to upstream bug.

See the code for rationale of the new way of handling things, how we work
around the bug, and the new added test for the required method.

Note that buffer_handler is NOT working, so no recording of audio samples is possible.
This is fixed in a subsequent commit.
cleanup of gst names and argv trick
Refactoring of audio file writing code, to have gstreamer do all of the work
Merge branch 'port-to-p3-gi'
