settings: Make mobile settings a first-class citizen

 * Nobody likes carriers, but let's not bury these settings behind
   10 layers of indirection. Many users (like me) who travel often
   will need to access these options frequently.
 * The top level switch disables mobile data.

Settings: Wise Order Settings

Android during the years has improved it's design and guidelines. This
change is meant to be a start point to redefine how settings are
handled.

Current Status:

- Give case sensitive to Section notes to improve their reading
- Move location settings to Networking
- Personal settings before Device settings
- Add advanced section (Users need to realize that some information
  could be misunderstood under that section)
