Added lodash for easy deep comparision and nice array utils.
Added incoming transactions directive. And added transactions property to appController's  so the incoming trabsaction directive inherits and use that property.
Added simple message filtering on the handler. Created a handleMessage function to filter message types and proxy them to the correct handlers. Created handleTransaction method that will check if the current address is valid and add the transaction into an array.
Added a method to add an amount to the currently displaying balance in the appController.
Removed default behaivour when receiving a message.
We calculate balance depending on transactions incoming via WebSocket.
