Original commit message from CVS: * s/gst_element_install_std_props/gst_element_class_install_std_props/ -- it just makes more sense that way * added jack element, doesn't quite work right yet but i didn't want to lose the work -- it does build, register, and attempt to run though * imposed some restrictions on the naming of request pads to better allow for reverse parsing * added '%s' to reverse parsing * added new bin flag to indicate that it is self-iterating, and some lame code in gst-launch to test it out * fixen on launch-gui * added pkg-config stuff for the editor's libs
