Issue: Book + BB-Code TOC

When the Book TOC is set to show, AND I forcibly put another TOC using BB-Code, the Book TOC breaks some HTML. Additionally, if I use the NO TOC BB-Code, the Book TOC appears anyway in the default position if I am custom-positioning the TOC elsewhere, and the article has no sections.

Fixed for the next build. HTML was broken because the TOCs were not added in position order, but rather the order they were found. Also, the default placement did not check for NO TOC for cases in which the article had 0 headlines of its own.
