Moved the private stuff into HaskellNet.SSL.Internal, so that
HaskellNet.SSL only exports Settings.
Updated minor version number for this quickfix release.
Hackage is reporting a build failure relating to cryptocipher, a library
which is no longer required with newer versions of tls/tls-extra.
Explicitly setting these library dependencies to the version I have
installed locally in order to try and resolve the build failure.
