[root] Status Bar Cleanup

Jan 19, 2017

[Fixed]
- The VPN and location icons no longer take any space for layout purposes.

[Added]
- Option to hide the screen mirroring icon (for an instance, when Chromecasting).

- Option to select which SIM card's mobile signal icon to hide.

- Option to hide the voLTE icon for OnePlus devices running Oxygen. Note: I also plan to add support to hide the NFC icon once Xposed is available for Nougat.

- Xposed checker since a lot of people didn't bother to read the description.

- Minor improvements.
