Logging Action Cable to STDOUT caused the development log to see double
messages like this:
```
Started GET "/" for ::1 at 2015-12-17 15:21:34 -0500

Now that Action Cable is part of Rails it doesn't need it's own logger
and will log to STDOUT via the local dev server here:
https://github.com/rails/rails/blob/master/railties/lib/rails/commands/server.rb
[ci skip]
Since Action Cable is getting integrated into rails/rails, the Travis
badge for rails/actioncable is not needed anymore.
Also following the standard of every other README to have `--` rather
than `-` to separating the name of the library from its description.
The application can have more than one ApplicationController and we
want Action Cable helpers in all controllers and their views so we
should hook in the same place that others helpers.
