[Chameleon] Billingual method of selecting map file?

[Paul Spencer]

If the app is still working then I can't think of anything else to test. 
  I was thinking about this some more and changing the map file will 
work (duh) for layer extents because the map widget keeps track of the 
current extents and re-applies them ... there may be other aspects like 
metadata set up by specific widgets that won't be carried over, however. 
  For instance, the ExpressionBuilder uses metadata ... there are others 
too but I can't think off hand what the side-effects would be.

Cheers,

Paul
