[KPhotoAlbum] gps search: a patch

For me, neither option is ideal. Option 2 (update on startup) will be quite 
frustrating, especially for users who don't use geotagging.

Option 1 is potentially better, but I would prefer it if the user gets a 
choice as soon as he/she enables the gps search.

I see at least one other option:
(3) Do not trigger updates to the exiv DB, and ignore missing gps values

A definite upside to option 3 is a low performance overhead. The downside that 
should not be understated lies in the potential confusion of the users.
