Update the Unicode Data and Algorithms up to Unicode 6.3.0

* Mongolian and Phags-pa characters have been given a Joining_Type
  classification for contextual shaping. As a part of these additions,
  one Phags-pa character has the Joining_Type value of L (Left Joining),
  which no character had been assigned before.
* The unassigned code points in the Currency Symbols block have been
  given the Bidi_Class property value ET and the Line_Break property
  value PR, to help implementations support new currency symbols,
  when they are encoded.
* Hebrew letters and basic punctuation marks have been assigned
  the newly introduced Word_Break property values Hebrew_Letter,
  Single_Quote, and Double_Quote.
* The Bidi_Class property has been extended with four new values
  for directional isolates.
