[documentation] Update WMS Server HOWTO with stricter WMS rules (option A is invalid)

[bartvde@…]

Option A: Use Only Parameters Required by MapServer
 
Simply adding
"VERSION=1.1.1&REQUEST=GetMap&LAYERS=yourlayername1,yourlayername2" to your
server's URL should generate a map with the default map size and all the
layers with STATUS ON or DEFAULT displayed, e.g.

This option is invalid now because Mapserver is stricter with WMS parameters.
WMS Server HOWTO has to be updated, this section should be removed or a more
complete WMS URL should be documented.
