[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
	- radio button in manage backups should be holo style (which breaks compile)
	- some resources are hardcoded, which prevents theming
