Add enum_column3 Gem and patched version for Creme Fraiche Gem

Just saw this entry (http://osvdb.org/show/osvdb/94679) and added a pull request.

Also add patched version for Creme Fraiche Gem. From the changes.txt (gem source):

BUGFIX: Avoiding shell injection attack by escaping shell characters.
The fix makes use of the escape-library. In consequence, the escape-gem
is added to the list of required gems and will be installed upon first
use of CrËme Fraiche.
