[AgileWiki] Making it all a bit faster

[Bill la F. <bil...@su...>]

I've now dropped the attributes command and the one index which only it 
used. My hooe was that this would be a significant improvement. However, 
the size of the database only dropped from 3360K to 3296K, a 2% 
reduction in size. The improvement in speed may be more, but likely 
nothing worth writing home about.

Conceptually it does make the database simpler, though I was able to 
remove only a small amount of code.
