- since specific heuristic Twitter & Blekko is not longer available or redundant with OpenSearchHeuristic, adjusted ConfigHeuristic to use OpensearchHeuristic settings only. For this the default OSD search target list is made available (copied) by default and the other configs are removed. - the return of QueryGoal.getOriginalQueryString includes the queryModifier, which are held separately in a modifier object, but in most (all) cases just the query term is expected, clarified and renamed it to QueryGoal.getQueryString which returns just the search term (if needed a .getOrigianlQueryString could be implemented in Queryparameters, adding the modifiers) - started to adjust internal html href references from absolute to relative (currently it is mixed). For future development we should prefer relative href targets (less trouble with context aware servlets)
