HTTP GET requests allow for multiple parameters to be passed that share the same name. For example, the following GET call to the Twilio lookups API allows for the 'Type' parameter to be specified multiple times.

Currently, when calling the setQueryParam or withQueryParams methods on a HyperRequest, the query parameters are stored in a structure, which means multiple parameters with the same name will simply overwrite the previous value.
Instead, parameters should be stored to allow multiple parameters with the same name, similar to how stacking multiple cfhttpparam tags would allow the same parameter name to be used (and passed) multiple times.
