Implementation of copyrights notice handling for Nokia online plugin.

Introducing classes QGeoCopyrightsCacheNokia, QGeoMapCopyrightsContext.
- QGeoCopyrightsCacheNokia: Provides shared copyrights fetching and
  lookup services and is common for all maps generated by
  QGeoTiledMappingManagerEngineNokia, hence its instance is owned by
  the engine.
- QGeoMapCopyrightsContext: Encapsulates copyrights info for last
  rendered frame per QGeoTiledMapDataNokia class, and is passed to
  QGeoCopyrightsCacheNokia::evaluateContext(...) to evaluate the
  validity of last copyrights notice upon signaling by base
  QGeoTiledMapData.
