[tycho-user] Heads up: needing to explicitly set surefire's trimStackTrace with Tycho 1.2

Since updating to Tycho 1.2, we noticed that our error stacktraces from failing tests were abbreviated. We're now explicitly setting surefire's `trimStackTrace=false`.  I spent an hour or two trying to track down a what seemed to be an odd NPE as the actual site was trimmed.

What's odd is that although Tycho 1.2 updated surefire from 2.17 to 2.19.1, the trimStackTrace setting, and its default to true, dates back to surefire 2.2.  I'm not sure what resulted in the change!
