Spambot Search Tool 0.10 - licence changed

When I create a new product, I typically include my standard licence/EULA in the package, and this occured when I modified and packaged the original spambot search tool created by Smurf Minions;

I've now changed the licence for this, to the Creative Commons Attribution 2.0 licence;

The version number is unchanged.
