fix bbox in execute template

[cehbrecht]

Overview

According to the wps 1.0.0 schema the bbox in the execute response should look like this:

<wps:BoundingBoxData crs="epsg:4326" dimensions="2">
          <ows:LowerCorner> -90.0 -180.0</ows:LowerCorner>
           <ows:UpperCorner> 90.0 180.0</ows:UpperCorner>
</wps:BoundingBoxData>

The schema has no entry for WGS84BoundingBox.

WPS Execute outputs are:

<element name="Output" type="wps:OutputDataType" maxOccurs="unbounded">

These can be Data:

<element name="Data" type="wps:DataType">

And this can be a bbox:

<element name="BoundingBoxData" type="ows:BoundingBoxType">
