[pLog-svn] wizard

[Jon Daley]

 	I don't know how much time I can spend on this, though I do want 
it fixed in the best way, so maybe I will make time.
 	I have been running the entire wizard multiple times on 1.1.  I 
don't think the version check is good enough - that will put us back where 
we were in 1.0, where we have these crazy checks in the code.  I will go 
through the wizard and see how much needs to be changed.  If it is just 
the trackbacks, I will fix that.  If it is more, I will probably come back 
to talk about it more - and have to restore a backup for my own blog 
probably...

 	I am working on the config table remove duplicate entries, and I 
think it will work well, I will probably check in the code soon.
