6.1.30 plus svc builder

Hi Rich and Jesse,

This branch contains all of the 6.1.30 PACL and Marketplace changes, plus all the filenames, numbers, and chapter references have been adjusted to fit in placeholder file 04-service-builder.markdown.

Jesse - If you would, please send me a pull request from a 6.1.x based liferay-docs branch, replacing the contents of this 04-service-builder.markdown placeholder file with your Service Builder content. But please preserve the header ID and ending transition currently in the placeholder file. Thanks!

I'll port over the event-listing-portlet and test it on 6.1.30 (EE GA3).

Thanks.
