[Chameleon] Geocoding, and rectangle query

[Julien-Samuel Lacroix]

Hi,
1) I didn't heard of anyone who did that. If you are willing to develop 
it or get someone to develop it let us know. We could add it in the 
official version. I think it would be a great addition.

2) For local data, the CVS version Query widget is now supporting 
rectangle queries. Simply add AllowRectangle="true" in your widget 
definition.
