OGC Filter Problems with custom output formats defined in templates
===================================================================

The getFeature requests have been changed so that http://www.opengis.net/ogc is the default namespace in filter expressions (e.g., filter operators no longer require ogc: prefix)
Now, more requests work.

0. a. roll=15BCC10007 and frame<156 works; this demonstrates that some and expressions work

   b. roll=15BCC10007 and frame>155 works with/without &maxFeatures ; this demonstrates that roll 15BCC10007, frame 156 exists and contains valid data.
