* fix handling of WebSocketConnectionClosedException
CLI
* witnessfeed: uses the new market ticker to calculate the current steem_usd price as base. When using support-peg the sbd_usd price is calculated from the internal ticker and used for quote.
* Witness: shows the rank and active rank (when it is below 250). virtual_time_to_block_num is calculated from num_scheduled_witnesses, VIRTUAL_SCHEDULE_LAP_LENGTH2 and vote_sum. This is then used to estimate the next block producing time.
* witnesses uses a proxy now, when set.

CLI
* updatenodes added, this command can be used to update the nodes list
NodeList

Nodes
* Node handling and management of url and error_counts is performed by the nodes class
* sleep_and_check_retries is moved to the nodes class
* Websocket, steemnodrpc were adpapted to the changes
Unit tests
* new tests for the nodes class
* tests adapted for websocket and rpcutils

Set use_condenser to True
Add unit test for hash_op

Certain transaction could not be verified, as the recover parameter in verify_message from ecdasig was wrong.
Signed_Transaction.verify() iterates now always through all 4 cases and returns all found key combination.

Unit test added for this case.
