smalltalkCI and Squeak 5.3/trunk

In case you're using smalltalkCI [1] for testing:

It's now using the latest OpenSmalltalkVMs for Squeak 5.3 and trunk builds. I've also updated the trunk images, so these builds should run a bit faster again (less time spent updating the image).

Please report any issues at [2].

Cheers,

Fabio
