Make test-notifs button in settings

The idea here is that we should make a really really minimal
notifications feature, where you can enable them, and test them, but
nothing on the server will automatically send them.

Once that's in, we can add client-side config, which we'll need to sync
to the server and act on, that says:

> generally, notify me:
> 1. Not at all
> 2. When my name is mentioned
> 3. When any message arrives
> For each channel, override the above with one of the same three
> options.

Later later, we might want to also add "notify me when a new channel is
made".
