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 // FREEBIE
