Lets nodes advertise that they offer bloom filter support explicitly. The protocol version bump allows SPV nodes to assume that NODE_BLOOM is set if NODE_NETWORK is set for pre-70011 nodes. Also adds an option to turn bloom filter support off for nodes which advertise a version number >= 70011. Nodes attempting to use bloom filters on such protocol versions are banned, and a later upgade should drop nodes of an older version which attempt to use bloom filters. Much code stolen from Peter Todd. Implements BIP 111
