Unicode tables are working

In between doing my taxes and working on a few OS X related build bugs, I managed to get the Unicode stuff to the point where it is ready to be checked in. Now we can do fun stuff like this:

    assertEq('\u01DE', Character.toUpperCase('\u01DE')); // Latin capital letter A with diaresis and macron

    assertEq('\u01DE', Character.toUpperCase('\u01DF')); // Latin small letter A with diaresis and macron

    assertEq('\uA764', Character.toUpperCase('\uA764')); // Latin capital letter thorn with stroke

    assertEq('\uA764', Character.toUpperCase('\uA765')); // Latin small letter thorn with stroke

And the whole set of tables weighs in at around 20k or so.
