Original commit message from CVS: * gst/gstpadtemplate.c: (gst_pad_template_class_init), (gst_static_pad_template_get), (gst_pad_template_new), (gst_pad_template_pad_created), (gst_pad_template_set_property), (gst_pad_template_get_property): Add "name-template", "direction", "presence" and "caps" properties, so that gst_pad_template_new() is just a thin wrapper around g_object_new(), which is better for bindings. (Fixes: #539772)
