includes commits https://github.com/AOKP/packages_apps_ROMControl/commit/ac20428f1b5799709c3ebac6ffee63457c40535a, https://github.com/AOKP/packages_apps_ROMControl/commit/e40920b6f1633508c029ee599c409e9c39c8f45c, https://github.com/AOKP/packages_apps_ROMControl/commit/1b9b63f44906839d4ef97796212dfa7f25cd7e0f

Also reworked the way headers are set for devices with different features.

Also restructured our use of getContentResolver() which was used over and over and over. Now we have protected global in parent BAKEDfragment and referenced from there. Based on this commit by zaphod https://github.com/AOKP/packages_apps_ROMControl/commit/c08d205d91e8c36b989b3570c9619c6e02a387d9
