and replaced old fist hash computation by new method that tries to find a gap in the current dht to do this, it is necessary that the network bootstraping is done before the own hash is computed this made further redesigns in peer initialization order necessary git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4117 6c8d7289-2bf4-0310-a012-ef5d649a1542
