v1.6 Submitted for Approval

This update addresses inconsistent display of guest names in all lists and emails.   We have always tried to respect the user preferences for Contacts app about whether names from contacts app should display First+Last or Last+First.  We are now going to respect this option across the whole application EXCEPT on the home screen.

From now on, in respect to user preferences of 'Contacts' app display order:

1. Names of bride and groom on the home screen will now always be displayed as FIrstname + Lastname (ignoring user preferences)

2. Names entered as 'Just a Name' will now display by taking into account the user preferences.  This gives a more uniform and predictable guest list display.

3. Multi Guest picker lists now respect the user preferences.

4. Emails exported for guest lists now respect order preferences.

On first Twitter login, a test tweet is no longer sent.
