* First block of data was being thrown on the floor during
  decompression in some cases.  This is now fixed.

* Debug output now knows about cookie related SWIs and won't claim that
  they are unknown SWIs.

* Transfers which are both Chunked and compressed work correctly now.

On the fly decompression now works.  Both deflated and gzipped files
are handled and will, if the server asks us to, be decompressed on the
fly during download.  (Chunked compressed downloads are untested)

Appears to work on the one server I've found to test against - more
servers need to be found. Particularly, we need to test unusual gzip
headers and interaction with chunking.

  Internet module are now vectored through a look up table so that the
  calls for an https request are sent via the AcornSSL module.   The HTTP
  module will only register https: protocol capability with the URL
  module if the AcornSSL module is present, thus allowing transparent
  addition of SSL support without requiring an update for the HTTP
  module.

* There is no encryption code in the HTTP module at all.  It is all
  confined to the AcornSSL module.
