- reachable function: If a message-sender writes another to ask a sked, I assume that his antenna is directed to this receiver-chatter.

If this causes that the sender-antenna is directed most likely in my direction (with a difference of ~25deg), the callsign will appear fat and green in the userlist. As the sender often propagates his frequency at the chat (that means, we have saved this already), there is a high probability to work him at this short term opportunity
- mark new connected stations
- made some UI improvements (Behaviour of messagefilter-radiobutton corrected)
- removed UI bug, caused if you send a message to your onwn station....
