Add function to get a list of all query values for a specific key

[m1h43l]

We need a function which returns a list (or in worst case an array) of query string values.

http://localhost/postalcodes?id=32423&id=32425&id=32429&city=Minden&country=Germany

Function suggestion:

list  il_getParmList(request : 'id');

or

array  il_getParmList(request : 'id');
