[WMS Server] Duplicate GetFeatureInfo formats

[jmckenna@…]

Testing with MapServer 4.6.0beta3, if i specify the following metadata in my
wms-server mapfile:

   "wms_feature_info_mime_type" "text/plain"

the following is returned by GetCapabilities on this server:

    <GetFeatureInfo>
      <Format>text/plain</Format>
      <Format>text/plain</Format>
      <Format>application/vnd.ogc.gml</Format>

Two things need to be done:
1- Avoid the duplicates in capabilities
2- Make sure that the type "wms_feature_info_mime_type" handler takes precedence
over the default text/plain handler

Fixed. mapwms.c now:

• checks if wms_feature_info_mime_type (pszMimeType) exists
  • if it does, check if value is "text/plain"
    • write out text/plain out ONCE either way
