12891	Support opening shapefiles in EPSG:3857	naoliv	naoliv	"While noticing that JOSM uses the Mercator projection (EPSG:3857) I exported a shapefile (from QGIS) using the same projection, but JOSM fails to detect it and offers to fallback to EPSG:4326.

Since JOSM already support and uses it, couldn't it also properly detect shapefiles using this projection?

Also, if accepting to fallback, coordinates seem to be all messed up (for example, node at `2422568°52'13.5""S, 5320119°37'09.3""W`)

The file is attached.
