Adds a padtemplate to an element class. This is mainly used in the _class_init
functions of classes. If a pad template with the same name as an already
existing one is added the old one is replaced by the new one.
@templ's reference count will be incremented, and any floating
reference will be removed (see gst_object_ref_sink())
