Save Ingen patches as working standard LV2 plugin bundles.

This allows you to create an Ingen patch in Ingen running as a Jack client,
save it, then load that patch as an LV2 plugin in any LV2 compliant host.

Eliminate (hopefully) all static data in the engine (for multiple instantiations in a single process).

More API/ABI stable interface for Ingen::Shared::World.
