add real size values (KBytes) of the DHT-In/Out-RAM-Caches to the PerformanceQueues page. A lot of users seem to tweak this value and it might help in finding the best size in relation to the peer's memory ressources.

         This is the current size of the word caches.
         The indexing cache speeds up the indexing process, the DHT cache holds indexes temporary for approval.
