api: invalid xml in soap_warnings.tmpl

Hello all,

When calling the api I received invalid xml for a specific situation (W22:
invalid charset). I traced the bug here:
  http://dev.w3.org/cvsweb/validator/share/templates/en_US/soap_warnings.tmpl?rev=1.11&content-type=text/x-cvsweb-markup

"</m:warning></m:message>" should be "</m:message></m:warning>"

I hope someone has the time to fix that. I'd love to help, but
unfortunately I don't have the time right now.
