WMS option for Cache-control max-age

The attached patch allows users to set the Cache-control: max-age value returned which each map image to a value in seconds, using "http_max_age" "nnn" in the WEB METADATA object. This should provide some speed advantages for tiled clients like openlayers that always access the same WMS GetMap URLs.
See http://www.mnot.net/cache_docs/ for a good primer.
