Thibault Saunier 02ab99fcbb validate: Rename gst_validate_add_action_type to gst_validate_register_action_type 
The _register naming corresponds much better to what the method does
and makes it more similar to how we refer to this kind of action in
GStreamer.

It is a last minute API change, but that API should not change anymore
after 1.4 is released.
