Improvements to password import.

[FIXED]     Importing of mpsites with passwords showing for
            stored password types.
[FIXED]     Don't try to show mail composition dialog when the user has
            no mail account configured.  This will crash.  Instead,
            show a friendly popup explaining things.
[IMPROVED]  Message of password export emails.
[FIXED]     Hierarchy of MPUnlockVC so password field becomes touchable.
