CII server improvement and fix for ws4py 0.3.6

This is a minor release containing mostly maintenance fixes arising from
recent changes to cherrypy/ws4py, some small documentation improvements,
and an enhancement to CII server support for when bound to multiple
network interfaces.

• Enhancement: CII server can transparently rewrite wcUrl, tsUrl and
  teUrl to take account of the network interface the client has connected
  to - enabling it to work when bound to multiple interfaces.

• Docs: README.md improvements.
• Switch from temporary to permanent fix due to cherrypy/ws4py bugs that have now been
  fixed. (#13)
