Added IntlCodePointBreakIterator.

Browse source 
Objects of this class can be instantiated with

IntlBreakIterator::createCodePointInstance()

The method does not take a locale, as it would not make sense in this
context.

This class has one additional method:

long IntlCodePointIterator::getLastCodePoint()

which returns either -1 or the last code point we moved over, if any
(and discounting any movement before the last call to
IntlBreakIterator::first() or IntlBreakIterator::last()).
