sync upstream
add checkpoint, seed node, and web_wallet
updating next child index after regenerate keys
Merge branch 'develop' of github.com:BitShares/bitshares_toolkit into develop
Use the variant of schedule_peer_for_deletion() that doesn't use a fc::mutex to protect the deletion queue.  This could greatly reduce the number of crashes in network code, but may mask underlying problems in the mutex or task switching code.

fix thread safety issue and prevent importing keys to contact accounts
Optimize get_item_ids() to use block_ids looked up in the database instead of calculating them from scratch each time.
Don't try to provide sync data to any peer who provides us an unreasonably long blockchain synopsis (they either have a screwed up database or they're an attacker)
Move the code that pushes sync blocks from the network to the client into a separate task, and force that task to yield for 0.4s every 1s to allow other network operations to take place.  When that happens, stop fetching blocks from the network until we've fully processed the backlog.
