[THREDDS #LAS-357036]: add WMS support for spherical mercator EPSG:3857 (for Google Maps)

Greetings John,

I've made a pull request to https://github.com/unidata/ncWMS and will make sure
it gets into the next release.

Cheers,

Sean

> Dear THREDDS Support,
> Could you please add support for EPSG:900913 to the list of supported map
> projections in your WMS GetCapabilities? This is a synonym for EPSG:3857
> which you added (at my request) years ago (2011). Some systems still rely
> on the EPSG:900913 instead of EPSG:3857, so advertising support for both in
> your WMS GetCapabilities would extend support to additional clients
> (currently, our GeoExplorer web client is balking at the lack of
> EPSG:900913). Again, this is the "spherical mercator" projection most
> frequently employed in online mapping GIS systems like Google Maps and
> Leaflet, etc. Many thanks!
