Preferences localisation

I just moved all the strings in the options window in the string database, making it possible to translate that part of the user interface. I also changed the name of that window from Options to Preferences, to match common user interface terminology.

This weekend I've been playing with a lift we rented. Yesterday I installed snow guards on the roof - 2*6m of tube secured near the edge, designed to keep snow and ice from falling down. Makes spring-time access to our front door a bit safer.

The feed of my 40m/20m butterfly dipole is also visible in this photo.
