Add Internationalized Domain Name Features.
Adds IDNConverter interface, ICUConverter using ICU for Stringprep.
Also updates Makefile and build.xml by adding path to icu4j to compile tests classpath,
so that icu4j.jar can be used in the tests. IDNConverter tests need StringPrepParseException from icu4j jar.

This patch is BSD-licensed, see Documentation/Licenses/BSD-simplified.txt for details.
Test-Information:
Added test for IDNConverter, which passes.
