Activities service in KDEreview

[Ivan Čukić]

Updated version in kdereview - it uses nepomuk in a much better way.

Since the ontology is not yet written, it uses a dummy link
http://www.kde.org/ontologies/activities#Activity
which can later be changed or made to redirect to a real rdf.

If anyone (Sebastian) has a better idea for the url, please speak.

I have a question, though. Since (per Sebastian's suggestion), the current 
activity id is stored inside the configuration file, and not inside nepomuk, 
is there a better way of getting the configuration group for a nepomuk service 
than doing it manually:

KConfig config(KStandardDirs::locate("config", "nepomukserverrc"));
KConfigGroup configGroup = config.group("Service-nepomukactivitiesservice");
m_currentActivityId = configGroup.readEntry("currentActivityId", QString());

Cheerio!
