* Demo portal is hosted in Google appengine. As the new appengine-java-sdk do not include (appengine Java 11 runtime) any web-serving framework, we need to check-in the servlet-api-2.5 jar seperately in java/demo/war/WEB-INF/lib, similar to commons packages.
* Making ant to compile demo class files at 1.8
Update doc references to refer to CLDR and the page of CLDR codes where
appropriate - it used to say ISO country codes were used, but they aren't.
Also updated to refer to two *or three* letter language codes since they may be three letters (we use the shortest defined one for a language)
Updating comments about leadingDigits field at territory level as well.
