Allow a LV2 plugin to mark the session dirty
If some plugin-internal state changes (GUI <> Plugin e.g. load a sample)
no ports change and the host does not know that the plugin state has
changed. The session may be closed without save.
This is a prototype using an ardour.org URI, pending upstream lv2plug.in
