enchange wms styling
* Enable opacity in SLD templates by splitting the corresponding
`_fill` value. The place of the change is in the handlers which are
specfic to geoserver templates. Adding it there keeps the way how opacity
is styled consistent with WFS styles towards the default values
in the database and the client.
