Part of issue 87, issue 63, issue 29, issue 30

In preperation for creating requester and proxy unit tests:

  o Tidied up some of the requester and proxy
  o Partially de-coupled requester from proxy
  o Fixed minor bugs:
    o is_valid_uri was not implemented correctly
    o http scheme validation had "http" instead of "https"
