* Add hooks HandleSectionStart() and HandleSectionEnd(). They are invoked to bracket package file section, so the handler can discriminate which section the attributes belong to. HandleSectionStart() features a return parameter _handleSection, which allows to handler to pick which sections it wants to handle. * "package dump" does now print the section names.
