[Chameleon] Locate widget

[Gianluigi Nozza]

I'am wondering, because this capability is a basic function in every GIS
application...
So I don't think I am the first looking for it.
Anyway I am very happy that the task is not so difficult (of course for
programmers)
so I hope to find answers to the question in a near future.
Still waiting for help here and in the mapserver user list....
