* This removes outdated info about the PS4 integration only supporting a single console. Support for that was added in 0.90 a few months back (PR here: https://github.com/home-assistant/home-assistant/pull/21302).
* Added field to sidebar that it's configurable from UI (that's the *only* way it can be configured in fact which the docs already mention).
* Also tweaks the instructions to reflect design changes that were made to Home Assistant Integrations panel (must press the + button to add integrations).
* Lastly updated a URL that was changed in the Dev Tools redesign in 0.96 release (`/dev-info` has now become `/developer-tools/info`).
