Map: Alternative transformations for selected coordinates

[klokan]

It may be practical to select alternative transformation for the selected coordinate system on the map page.

Selection similar to this: http://jsfiddle.net/klokantech/3cfnA/1/ probably - under the name of the system.

If the person goes to map directly from results we can preserve the list of results in suggesting next transformation.

Alternative coordinate systems may be suggested also by querying API for a country / region on given lat/lon (retrieved by Reverse Geocoding Service of Google Maps API) and zoom level of the map.
