URL / POST content should available in decoded fields

When accessing data that has been appended to a URL or has been posted to a LotusScript agent, you usually write yourself some routines to split query_string_decoded or request_content from the ContextDocument. Everyone has these routines and everyone struggles with de-/encoding or manipulation some of the values inside those containers.

There should be methods to generate items from those two sources, to access specific items (e.g. via getURLParam-function), manipulate them (getParam/setParam) and generate a new URL or POST from these values to be passed to other agents / systems etc.
