Support OSM XML metadata (timestamp, etc) about openlayers

I think it would make sense to add that metadata as a configurable metadata property for each feature. Do you think you'd be able to create a pull request?

Hello, I appreciate the reply. I tried for a couple hours to modify the existing osmxml.js part of ol.js.map offline to parse the timestamp with getAttribute similarly to how lat and lon are parsed, but was unable to make any headway. I think it's beyond my capabilities unfortunately.

The easy (and obvious) workaround to this was to simply convert it to GeoJSON using osmtogeojson which adds the metadata tags as feature properties. So it's effectively solved.
