Unable to read query params in a POST method

[LevitatingBusinessMan]

The current logic around handling query params is flawed.

Parameters are only drawn from the query string on GET or HEAD requests.

The correct solution would to not draw the parameters either from the POST_DATA, stdin or the QUERY_STRING depending on context.

I think there should be independent variables for POST/form data and the query paramaters. Something like @form and @params.

For now I am working with this patch: https://github.com/LevitatingBusinessMan/cgi/commit/e0501efab6f023a987081be60884090547554a17
