Reorganize settings

[cstiens]

@n8fr8 We discussed this on the product scrum and are onboard with this reorganization of settings. Mainly, we have just done some re-grouping and editing of the section names.

One bigger change that I recommend we do, is to add the accounts into the main settings view rather than having the separate 'My Accounts' view. The primary reason is to achieve parity with iOS. Let us know if you want support from @N-Pex on this UI.
