uri-library lacks support of percent-encoded query value

[hammurapi]

I need to parse URIs which contain arbitrary characters in the query value. To be able to do this the URI library needs to be able to decode the percent-encoded value string.

Here is an example : http://a/b/?q1=question-mark%3f&q2=ampersand%26 The query parameters of this URI should result in these decoded parameter-name parameter-value pairs: q1=question-mark? q2=ampersand&
