CCleaner package now adds a registry key which prevents Google Toolbar installation, fixed Ketarin job for CCleaner

In some cases the CCleaner package automatically installed the Google Toolbar. This modification of the `regAdd.ps1` file prevents it.

The Ketarin job for CCleaner wasn’t retrieving the version of CCleaner. I added a regex to fix that.

I already pushed the updated and fixed version to the Gallery (http://chocolatey.org/packages/ccleaner), so everything you have to do is to merge this PR and import the fixed `ccleaner.xml` into Ketarin.
