Feature/le big rebase

This is basically a rebase of our current dbpedia spotlight branch on Jo Daibers' quantized counts implementation. Server now uses around 8Gigs of ram (as opposed to 15.) We also made our relevance scoring work with that.  At the moment, this is WIP and should be only used to spot potential pitfalls in the code. Once we are sure the quantized counts work, we could roll this out.
