Hello Ada, 

Sorry for the late reply but I was enjoying a 2 day "vacation".\\ 
I've uploaded snipsnap jar, although keep in mind that other modifications in the source code are made. All the modifications I've done are documented in the blog and since you've already read my posts I know you're aware of them.

Also, count with an available SVN tree by tomorrow! (if you're interested)
