Improving WSJT-X integration

It is a very special release, even if not too big, because the work has not been done by EA4K 🙂

KLog 1.4.6 changes have been coded by EA5WA who is working hard to understand how KLog is done and sending many improvements, comments, testing support to the users and during the last weeks also code! (Congratulations!)

We have also changed QRZ to Callsign, something that has been requested by users 🙂

I hope you enjoy KLog and Thank you Juan Carlos for this release!
