Send notification to user after each client deploy

[joelmoss]

Currently when the client is deployed, users are not aware of it unless something breaks due to incompatibilities between the old client that they currently use, and the rest of the system (server, sharejs, etc.).

We should show a notification to let them know they have an old version, and that they should reload the page to get up to date.

Thoughts on how to do this?

[dignifiedquire]

We could use the the socket connection to sharejs, add a duplex stream on it and communicate the client version checking if it's the latest and if not show a blocker asking the user to reload.

Should it be a blocker or just a notice?
