an iteration of key elements in kelondroTree databases is no longer supported.
this is now replaced by an iteration of kelondroRow.Entry objects from the database
Iteration of keys from the database was mostly followed by retrieval of the row
from the database, whcih caused unnecessary database load.
The index selection was also redesigned to use the new row iteration methods.
This affects many funktions, most important is the DHT selection routine which is now much faster.
