The chat and twitter should be more accessible

[ligi]

As A user I would like to see chat-messages and tweets while viewing the map on a phone mounted to my bike when they arrive

When a new chat message arrives A Snackbar pops up and displays the message

When you click on this message Then you get to the chat part of the app

When a new tweet arrives A Snackbar pops up and displays the tweet

When you click on this tweet Then you get to the twitter part of the app
