Updated phone formatter (#241)

* Add locale and libphonenumber libraries.

* Update country code information

Updated existing country codes, fixed incorrect NANP codes for member countries (as well as several UK based ones).

Also added in Country Name to ISO country code mapping array for use with libphonenumber.

* Convert phone number formatting to use libphonenumber

libphonenumber parses phone number more consistantly than the old regex's that mismatched number on a regular basis.
