change ownership of processor window-proxy

fixes crashes:
* If the Editor-Mixer shows a channel with a plugin that
has been edited in the Mixer, double-clicking the plugin 
will try to bring up a 2nd instance of the plugin-UI.
* When closing Ardour both the Mixer and the Editor-Mixer try to delete the underlying plugin, resulting in a double free.
