Hey everyone!

If you're using acts_as_taggable <= 1.04, (erm, any version, I
think..) please fix your local copy right now!  There are numerous sql
sanitization holes in this library.

I notified Obie of this over a month ago, so hopefully he's fixed it.

How to tell lif you're vulnerable
Make a tag with a single quote in it.  See if raises an error.
Now, go delete your entire database.

How to fix
add/change the last line of split_tag_names

tag_names = { |name|
  ActiveRecord::Base.connection.quote_string( }
