[fusion-dev] map query in Fusion 2

[Benoit Begin]

The query method no longer works the way it used to. Before, it would call
Query.php in the backend and allow you to generate a new selection via an
alphanumeric filter and/or a spatial filter. The new query method now calls
the QueryMapFeatures directly from the mapguide fcgi agent. So basically,
the functionallity has it used to exists is no longer present, as far as I
can tell.

You can, easily enough, bring back the code from the old query method into
the new Fusion 2.0. I copied over the query method from the previous version
and named it queryEx and made it use the same callbacks as the query method.
It worked fine for me and gave me back the functionality I needed from the
API. It's kind of a crummy fix, as my own code needs to work on either
pre-2.0 Fusion and 2.0 fusion. Still, it works.
