Rhodey Orbits d8521637bb use Locale from DynamicLanguage for displaying dates
1) fixed DateUtils to use SimpleDateFormat for everything because it respects Locale
2) added getCurrentLocale() method to DynamicLanguage
3) allow PassphraseRequiredActionBarActivity.initFragment() to accept a Locale
4) updated classes that depend on DateUtils to pass down Locale from DynamicLanguage

Fixes #2684
Closes #2725
