Docs refresh

[asvae]

Updating docs is a bit problematic. As you can have update happen when user has page loaded.

If they try to navigate to some page - they might have an issue, as module might be not available anymore.

So we want to introduce some solution to make user interaction seamless.

Couple of ideas:

• keep multiple versions of bundle on server (let's say up to 24h), each in its own folder.
• sometimes send a request (to some json, where version is defined?) and if anything is changed (flags or version) - present user with update dialog similarly to what other docs use. This is not ideal as it requires action from user.
