Support X-PHONETIC-FIRST-NAME and X-PHONETIC-LAST-NAME

[t-bucchi]

fix #251
I wrote the patch to support X-PHONETIC-FIRST-NAME and X-PHONETIC-LAST-NAME properties (issue #251) based on v3.3.0.
This patch changes two things:

• Add "Phonetic first name" and "Phonetic last name" to detail view.
• Add "Phonetic first name" and "Phonetic last name" to sort keys.

In Japan, a phonetic (pronounce) name is one of the essential feature for address book.
Because, the Kanji character has many pronunciation.
So, usually contact list is sorted by phonetic order.

NOTE: The X-PHONETIC-FIRST-NAME and X-PHONETIC-LAST-NAME properties are
already normally supported on Android and iOS.

Could you review and merge my code?

Thanks!
