[mapserver-dev] default values when using url overloading

[Steve Lime]

Problem is that it's the presence of a parameter in the URL that causes the code to 
check if something needs overloaded. So, for each url variable 'key' we look for %key%
in supported places and also apply validation (if supplied).

To do this we'd need to be able to define a list of supported keys and work through 
that instead of the entire list passed as part of a request. With that it would be easy
to define a default somehow, likely through metadata.
