Bug 570727 - [codemining] Codeminings computed multiple times

if the same CodminingReconciler is added multiple times (e.g. for
different content-type, from different plugins for the same content
type) the codeminings are calculated for every change multiple times.

To fix this a check is added that the reconcilingstrategy is only
installed once for a given viewer.
