[1/2] OmniGears: OmniBackup
A backup solution using the system backup service (same as "adb backup") integrated into system settings.
Settings->Apps->installed app: backups section, create, restore, delete backups for the app
Settings->Security: backups section, manage backups, set backup location, history, password
Can someone with multiuser that these additions work correctly? (they should only show up for the device owner)
Known issues:
- backup/restore errors are not reported, https://code.google.com/p/android/issues/detail?id=32830
Settings: https://gerrit.omnirom.org/#/c/6331/
 PS 13: Change ManageBackupsActivity to have tabs, formatting fixes, do proper service connection
