Preferences - Messaging - respond to QRU requests within distance

I just did a reinstall of QTH with the 1.0.6 version and noticed that the default value for the “distance” field below is 80,47km for non-imperial-system users. My guess is that this value was simply converted from its default ‘miles' value (50 * 1.6), hence the weird default distance. This is not a big issue but looks weird when you run the program for the very first time.
