Settings are now only on home screen as it directly relates to what user might want to do. It is highly unlikely that they would jump from any other screen to settings.
Log is no longer main destination as it's not used very widely; it's been moved to Superuser screen. This screen now encapsulates all root-related stuff.
Home screen is now strictly info-based, except install buttons, of course.
- correct 'booloader' typo breaking bootloader entry
- remove extra bootloader entry Shell.su line which is unnecessary since it's covered by reboot()
- revert to using `reboot recovery` for recovery entry since `svc power reboot recovery` triggers a very disconcerting "Factory data reset" reboot dialog on many devices
- add Reboot to EDL mode option for good measure
