on irc, killes suggested that nid be indexed. rather than provide
separate mysql/pgsql schemas i've just made vid, nid a joint primary
key. 


i should also mention, i've upated quite a bit of other code in the
module to follow the current practices in core (with the exception of
the long forms format). like, removing the hook_link implementation as
it's handled by tabs now.

I was looking information on the revision system when I came across a
comment [1] from someone confused by the changes. In there they asked
for node_example.module to be updated to demonstrate revisions.
Thinking that was a good idea I started on it. 


In the process I realized that it was kind of kludgy that you had to
implement hook_nodeapi() to delete revisions. I'm working on a patch
for that so I'm putting this aside for the moment. 


Attached is a patch that adds revision support EXCEPT for deleting a
single revision.
