CGPublisher upgrade

Just a little upgrade today, with lots of behind-the-scenes work on big new features.
  • Added 'Display Author' field to diaries
  • Conference registration "badge name" has none of the usual name restrictions (all lower- or upper-case are allowed)
  • Removed a lot of unnecessary entries from My Works listing
  • More fixes to email gateway to handle stupid mail clients
  • Much better customisation of webspace stylesheets
