Adding MapServer support to WFS-NG

modules/unsupported/wfs-ng/src/main/java/org/geotools/data/wfs/internal/AbstractWFSStrategy.java
- Removes an unnecessary System.err.println

modules/unsupported/wfs-ng/src/main/java/org/geotools/data/wfs/internal/WFSClient.java
- Creates a MapServerWFSStrategy object if the WFS_STRATEGY is explicitly set to 'mapserver'

modules/unsupported/wfs-ng/src/main/java/org/geotools/data/wfs/internal/parsers/GmlGetFeatureResponseParserFactory.java
- Adds MapServer supported formats to the list

- Removes code that was adding a full-extents filter to a WFS GetFeature request when no other filter was specified.  
- Adds code to reformat gml:Box coordinates for WFS 1.0.0 BBOX filters.  Some older versions of MapServer do not support the following format: <gml:coord><gml:X>-59.0</gml:X><gml:Y>-35.0</gml:Y></gml:coord><gml:coord>< gml:X>-58.0</gml:X><gml:Y>-34.0</gml:Y></gml:coord>.  The code reformats the gml:Box coordinates into <gml:coord><gml:X>-59.0</gml:X><gml:Y>-35.0</gml:Y></gml:coord><gml:coord>< gml:X>-58.0</gml:X><gml:Y>-34.0</gml:Y></gml:coord>
- MapServer returns features in the ms namespace when no other namespace is specified for a feature type.  The translateTypeInfo method was added to address this issue.  However, it only worked for 1.1.0.  "wfs" is the default namespace for MapServer GetCapabilities calls.  For 1.1.0, MapServer includes a prefix with the wfs XSD declaration, but does not include one for 1.0.0, only a URI.  Therefore, the code did not work for 1.0.0.  The code now checks for a prefix or the wfs XSD uri.  

The MapServerOnlineTest unit test covers all code changes.
