[BlueBream] Documentation updates status

[Baiju M]

Hi All,
         I have done few documentation updates recently.

- Removed obsolete pages from wiki
- Removed the "unfinished" status at the top of every page in Sphinx docs
- Moved Creating Local Site Manager to Sphinx:
  http://bluebream.zope.org/doc/1.0/howto/localsitemanager.html
- Added reference labels:
http://sphinx.pocoo.org/markup/inline.html#cross-referencing-arbitrary-locations
- Added description to standard events reference page:
http://bluebream.zope.org/doc/1.0/event.html
- Cleaned up ZPT - removed Zope 2 related things:
http://bluebream.zope.org/doc/1.0/manual/zpt.html
  (Still there are few Zope 2 - ish parts there)

We should have a good documentation before 1.0 release.

Regards,
Baiju M
