Nepomuk

I suspect some of bloat, and a contributor to the claims that KDE "feels 
slow," has to do with the sheer number of databases. I'm experimenting with 
building a KDE system by hand. So far, three separate databases are installed:

* MySQL for Akonadi
* Sqlite for Quassel
* Virtuoso for Nepomuk

Quassel is hardcoded to depend on Sqlite. Akonadi can be switched to that as 
well, but some docs on KDE.org warn against that, claiming performance will 
suffer. Nepomuk is similarly wedded to Virtuoso through Soprano. Surely there 
has to be a better way.
