* Configure everything via services.xml, removing lots of
duplicated layouts and code
* Check that this works on phone and tablet
* More to do: get rid of abstract class with only one
subclass (AccountServerBaseFragment), remove as many
references in Email2 to specific protocols (a lot has
already been done)

* Put most setup parameters in services.xml (at a later date
these can be obtained directly from services, but we're not
in a position to modify Exchange until next OS release)
* Make more parts of setup reference service information rather
than directly refer to specific protocols
* Base account type buttons on declared services
* Continue the effort to make Stores obsolete
