#75 rewrite of the bounty fetch system

instead of writing my own complicated back and forth I just changed the
wantedFetch to have a "personal" mode additional to the normal mode used
to fetch the bounty list for the cops. There are some downsides doing it
this way, biggest being network traffic - to prevent any negative impact
bounties are only refreshed every 60 seconds.
