Add protocol for loading and unloading bundles
Currently this is only really useful for refreshing updated bundles. It will trigger the appropriate load and unload in the Lilv world, but the set of plugins and presets is not updated and clients will not be notified of any changes. git-svn-id: http://svn.drobilla.net/lad/trunk/ingen@5807 a436a847-0d15-0410-975c-d299462d15a1
