* 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.
