[Chameleon] Image format of map

[Paul Spencer]

I think we need a way to control this from the application rather than 
only being able to do it through the configuration file.  In fact, you 
actually can change it in the index.phtml file but it requires some 
mapscript to do it.

The original reason for having it in the configuration file was because 
we were working only with Web Map Context documents so there was no map 
file to start with ... hence no image format.

I think a reasonable change would be for chameleon to use the map file 
image format and to move this configuration parameter into the cwc2.xml 
file so that it only affects the service instance mode.

Comments and suggestions welcome
