* whisper skeleton * basic message store * rallying and message logic * pass host info to network protocol handlers * choose who starts rally based on node key * module reshuffling * mining messages * prune messages by low PoW until below size target * associated error type for ethkey generators and `OsRng` generator * beginnings of RPC * generic message handler for whisper * reshuffle code order * standard payload encoding and decoding * basic crypto * minor restructuring of net code * implement shh_post * merge? * implement filters * rand trait for hash types * filter RPCs for whisper * symmetric encryption of payload * pub-sub * filter tests * use only secure random IDs * attach arbitrary protocols to network * basic integration of whisper into Parity * eagerly prune low PoW entries * broadcast messages with salted topics * node info RPC * fix import * fix leading zeros calculation * address minor grumbles
