Wear brightness control

This simple application is primarily for using with HuskyDev watch faces.

It was created as a consequence of changes in the permission model on devices running Android 6.0.

Beginning in Android 6.0 (API level 23), users grant permissions to apps while the app is running, not when they install the app.

For adjusting of the screen brightness user must grant special permission "MANAGE WRITE SETTINGS". There is a special system UI for this request on the phone, but on the watches, this system UI is missing. Android Wear platform doesn\'t implement the system UI required for the user to grant these "super-permissions".

Solution for this issue is create new standalone application targeting older version of Android, so no need to request permission while app is running.
