Merge pull request #716 from tan9/master

Add/update Chinese (traditional) translation.
Fixed a mess-up in the changelog.

Not sure what has happened --- perhaps some of the markers were off and
that confused the update script?

Will need to watch out for the next RC run.

[FIXED JENKINS-12542] upgraded to XStream 1.4.4

There are several incompatibilities in XStream 1.4 that resulted in our
changing the core, but according to the text search on all the public
plugins, none of these changes affect the 600+ plugins we have today.

However, it is still possible that there are some parts of XStream 1.3
that plugins depend on but the core doesn't depend on --- we won't be
able to tell those problems at this point.
