Update commits with LPS and some comments

Hey Mate,

Everything seems perfectly fine to me; thank you very much for the pull.

I've one more question regarding this kind of references: what will happen with the test **com.liferay.portal.lar.PermissionExportImportTest**? This test has a reference to the Bookmarks portlet which, potentially, will not be available in the core anymore.

What do you think?
