[Chameleon] OGR and Query Widget

I'm pretty sure that I've seen it used without problems.  Some things to 
make sure of with querying:

* layer has a 'template' value set - doesn't have to be valid:

TEMPLATE "ttt.html"

* layer has a non-zero tolerance set


* layer is ON (DEFAULT should work too, but try ON)

* there was a bug in the query code from php_utils (found under common 
in chameleon) that caused problems if there were also WMS layers that 
were queryable but that didn't return results.  You will need to update 
from CVS until the next version is out (no timeline yet, sorry)
