Liferay IDE 2.0 Updates

Hey Jim,

Here are the updates for our *Working with Liferay's Developer Tools* chapter related to Liferay IDE 2.0. This chapter is fully updated, except for the required versions for JRE, Eclipse, Portal, etc to run on IDE. I sent a email to Greg and will update the version requirements when I hear word back. Besides versioning, Liferay IDE is now fully implemented into this chapter. Thanks.
