OSM widget added.

This widget allows user to browse map using OSM tiles, from openstreetmap.org (classic view) and opencyclemap.org (relief/landscape view).
The API to translate query to coordinates is from Geonames, which provides a key limited to 2k request/hour. Open-Sankoré could register a normal key or contact the administrator to get an unlimited key.
