Expanded the Attribute set available for Tomcat's Server.xml

Of the several Tomcat Cookbooks available in the supermarket, I think yours is the best! It's only downside is that it doesn't offer much in the way of config options for Tomcat's Server XML. I've added some (namely, what I plan to use personally), and set up defaults as well. 

For people familiar with Tomcat, most of these new attributes should be self-explanatory, but if you have any questions about them, I'd be more than happy to answer for you.

Thanks :)
