Breaking:

• Add proper XML Exception when service parameter disabled / invalid or missing
  In the past MapProxy returned WMS Capabilities when no explicit service parameter was given in
  GetCapabilities requests. With this change, an OGC exception will be returned instead.
  Invalid service types now also return a proper exception instead of an internal error.
  Besides, the status code of exception responses now have a 400 or 500 code instead of 200
  for better conformity.
