[Interest] QUrl: changing a single query item's value

[Pritam Ghanghas]

Hi Mandeep,

I have used removeEncodedQueryItem() and addEncodedQueryItem() in the
past for such requirement. Not exactly inplace modification but it
works. It adds the new item at the end of the original list. if order is
important to you, it may not work.
