Yet another CRaSH beta (21)

Nothing fancy, in it, mostly bug fixes (in particular for SCP CRASH-23 and CRASH-24).

I updated also the Google Code page to add links to GitHub where the project is now hosted and the online docs now have the PDF and the Javadoc.

Finally the project CI is now Jenkins hosted by my friends at Cloudbees. A special thanks to Arnaud for helping me setting this up.
