Simple Patch for Themers for the Subscription page.

Should apply against the latest -dev release of the 2.x branch - I needed to theme the width/style of the table on the user profile page for the subscriptions "Name, Description, Action" table, so I added class attributes of _name _desc and _action instead of _cell for all three.

See attached patch, and patch to the CVS branch if you would like. I assume you'll be rewriting more of that file, but for now, this is a quick and easy way to let themers like me make things look pretty without much hassle. (There are probably other areas of this module which could use themer review, but for now, I hope this is helpful!).
