Original commit message from CVS: * examples/gstfile.py: Moved the Discoverer class to gst.extend Now works asynchronous... bl**dy fast :) * gst/extend/Makefile.am: * gst/extend/discoverer.py: Discoverer has landed in extend and is now asynchronous. It emits a 'discovered' signal when it has finished.

# _ in an object-oriented way (Discoverer class)
|

# _ subclassing a gst.Pipeline
