Cache coordinates and place names for geolocation lookups about elodie HOT 2 CLOSED

Here is an initial version
#48
Currently database look up don't scale well, but I'm unsure if it is a real problem as it might not contain a lot of entry's. (In my test I got 84 entry's for about 1 year of photos, with some travels)
Some item needing input, mabe in this commit or in a followup commit if you like to keep each commit simple:

• Should I add a simple lookup runtime cache for 3-5 last items, I think most new photos added will be from the same or few areas.
• The 3km range, should that be configurable in the config.ini file or is that overdoing it?
• Should we cache Unknows locations so they do not need to be re-lookedup on?
• Spotted that the Db is created 2 times per image (one time before) and the db-files are re-read everytime.

Interesting project this one you manage to create something I longed for!!!
