* For each of incoming, outgoing, exchange fragment, create a "settings
mode" which slightly alters the layout for use in AccountSettingsXL.
* Build a settings mode wrapper layout around the basic fragment
* Add new constructor to set "settings mode" and select layout
* Add wiring for cancel/next buttons in the fragment
* AccountSettingsXL configures each fragment in its settings mode
* Remove old actionbar "Next" options (no longer needed)
TODO: Pixel perfect adjustments, colors, fonts, etc.

* Fix incomplete tracking of mLoaded flag
* Defer validation on automatic reload of fields (on rotation)
until reconstruction completes and we're ready to do validation.
* (For Incoming only) Split loadSettings into configure and reload phases;
We need to configure the UI every time we restart, but we don't want
to reload & overwrite user-entered values on rotation.
* (For Exchange only) Properly show/hide trust certificates options on
rotation, and show/hide divider too.
