Move material from wiki to the manual

[Henrik Ingo]

The Drizzle wiki: http://wiki.drizzle.org/
contains a lot of material that really should be in the manual: http://docs.drizzle.org/

The task is to clean up the wiki so that
 - if text clearly belongs to the manual, move it there, then delete the wiki page
 - if similar text already is in the manual, see if there's still something you want to merge, then delete wiki page
 - if text is obsolete, just delete wiki page

To contribute to the Drizzle manual, you need to use bzr and write in Sphinx markup. See http://docs.drizzle.org/contributing/documentation.html?highlight=sphinx

Ok, so for clarity: Note that some of the material in the wiki really belongs in a wiki and should not be deleted.
