8.0 doc

[Andreas Pflug <pgadmin(at)pse-consulting(dot)de>]

Hi Dave,

again we have a bunch of doc changes, and I'm quite tired manually 
adding them to pgadmin3.hhc again and again (apart from that being quite 
error-prone). We really should have it generated from sgml.
I'm completely unfamiliar with jade, and there's a lot of other stuff 
for me to do so I'd be glad if some shiny knight would appear creating 
the basics. If it makes sense, we could convert the pgadmin pages to 
sgml as well.

Regards,
Andreas
