Find appropriate setting that would make it possible to run multiple instances of the ada-ae stack

First investigations: MaxQueryMem, NumberOfBuffers and MaxDirtyBuffers do not have any effect on annotation queries (per movie, text search, value search). Runtime is only dependent on the number of annotations returned.

Querying all scenes (used by retrieving movie metadata) is running unusually long (see https://github.com/ProjectAdA/ada-ae/issues/41), but only until virtuoso is restarted once.

Memory requirements have been reduced and long running queries have been optimized.
