Add multipoint, multipolygon, multilinestring geometries support to define an area in a spatial filter, when a GetFeature request is sent to a WFS 1.0.0 server

[nsavard]

When a GetFeature? request is sent to a WFS 1.0.0 server with a spatial filter that defined an area with a multipoint, multipolygon or a multilinestring geometry, an exception is returned. Actually the polygon, line and point are supported in the FLTInsertElementInNode function found in mapogcfilter.c.

We need to support these geometries in a WFS filter in order to go through the OGC CITE tests. See wfs:test1.0.0-basic-getfeature-filter-spatialoperators-contains-get-4 (s0008) wfs:test1.0.0-basic-getfeature-filter-spatialoperators-contains-get-7 (s0008) wfs:test1.0.0-basic-getfeature-filter-spatialoperators-contains-get11 (s0008)
