Trollius10

Websockets examples don't work on Python 2.7 or 3.3 with Trollius 1.0. Here are some fixes.

My changes drop support of Trollius older than 0.3, but it's time to move on! It's hard to support all Trollius releases, the API changed a lot before Trollius 1.0. IMO it's easier to require Trollius 1.0 or newer.
