[Spambayes] New web training interface for pop3proxy

[Tim Stone - Four Stones Expressions]

I wouldn't spend a whole lot of time working this right now, as Neale, Alex, 
and I are about to merge our stuff in, and quite a bit of this code has at 
least changed places, if not been altered a bit.  When you see the merge, go 
ahead and test this stuff again.
