Original commit message from CVS:

* gst/gstbin.c:
doc updates
* gst/gstregistry.c: (gst_registry_scan_path_level):
fix for a nasty little missed situation where an installed plug-in
which was in the cache did not get overridden by an uninstalled one
which was earlier in the plugin path because the newly created plugin
for the uninstalled one (not in the registry) didn't get its
->registered set to TRUE
