    accountsMonitor: Store accounts in a Map
    
    Accounts are serialized for actions and settings, however we
    currently have no good way to deserialize them, falling back
    to TpSimpleClientFactory.ensure_account(). Storing accounts in
    a Map instead of an array will allow us to provide a lookup
    function, besides making the accounts monitor code itself
    slightly cleaner.
