Original commit message from CVS: Lots of modifications to the plugin system. - Added a GstPluginfeature object that serves as a base class for all plugin contents. - changed the plugin API, everyhting is now added with gst_plugin_add_feature - typefactories are named now so that they can be located easily and filled in at plugin load. - mime types like "video/raw image/raw" are gone for now. - lots of plugin updates (style and API changes) - tested with an without registry. - updates to various tools. - added a little testsuite to test/show how you can load plugins (4 modes) Test this one, Almost everything has changed :-)
