Version 7.4.0 released

The major change in this version is moving to deterministic wallets. Rather than each account in your wallet having a key that needs to be backed up separately, all accounts are associated with a single "wallet seed". This number is the only number you need to back up in order to recover all your account numbers in case of data loss.

Wallets upgrading from previous versions will be almost seamless. When you unlock your wallet, a random seed will be generated. If you view your accounts under "Advanced" -> "Accounts" any old adhoc accounts that have a balance greater than zero will be displayed in red. If you have adhoc accounts with no balance, they are not displayed. You can generate new deterministic accounts with "Create account" and we recommend you send balances from adhoc accounts to deterministic accounts.

Please back up your wallet seed according to the updated instructions https://github.com/clemahieu/raiblocks/wiki/Wallet-Backups

A "stop" RPC was added to shut down the node gracefully.
