Use request=GetMap instead of request=map

[cwhitney]

Reported by Andrea Aime:
"I noticed wms requests do use request=map instead of request=GetMap? as mandated by the WMS 1.1.1 standard. GeoServer tolerates this and returns a map anyways, but I guess it would be better to make fully compliant requests?"

I confirmed this, and specifying the request parameter in the properties file does not appear to override this default value.

I added a patch, although probably not needed since the changes are obvious. The properties file will not override this value-- but that feature doesn't need to exist.
