Relevant ticket: https://github.com/orgs/peerplays-network/projects/1#card-32596178

• Added missing getAccountsFor(). This is a function that the latest version of the UI is referencing.
• generatePPYKeys: Just used to communicate with the plugin
• updated plugin to include missing functionality required for proper ui operation
• some data flow fixes
