[Usability] “geocoder” is geeky jargon

[KAMiKAZOW]

I'd like to propose that the GUI uses a different term than “geocoder”. I don't think a normal user would understand it and – quite frankly – even I as an active OpenStreetMap contributor had to look it up as I just had an somewhat educated guess what it means.
I think “address lookup” or something like that would be easier to understand.

Alternatively the description text (currently “Enable, disable…”) could explain what it is.

PS: Your project is totally awesome. Keep up the great work.
