Bug fixes, improvements, and features for 1.5.0

[ndw]

• Added support for a search box in the persistent ToC. It filters the ToC entries based on what’s input.
• Added the persistent ToC link to the home page, where it had previously been suppressed.
• Reduced the size of component titles in articles.
• Added an option to suppress “trivial” Tables of Contents. A top-level ToC that consists of a single entry is suppressed by default.
• Reworked how index entries are generated. Where there used to be one index entry per section, there’s now one index entry per indexterm, numbered sequentially. All the terms in a single section are grouped in a span. You can disable this with $indexed-section-groups.
• Added bibliography, glossary, index, acknowledgments, colophon, and dedication to the ToC for article.
• Reworked a bunch of build infrastructure.
• Fixed What does class="no-js" do? #108 by making sure the ‘no-js’ class gets turned into ‘js’ if JavaScript is available.
• Fixed Make the catalog available automatically #110 by copying the catalog into org/xmlresolver in the jar file.
• CSS improvement, don’t highlight code elements in ToC entries with borders or background colors.
• Fixed ToC generation for nested sections is completely wrong #111 by interpreting ‘unbounded’ correctly in ToC section depth.
• Added support for db:templatename
• Reworked “line” styled verbatim environments with new ‘verblines’ class.
• Tone down the style of literals: lighter border, don’t make them nowrap.
• Fixed Fix purl #104, change http: to https: in purl.org URLs
• Fixed Implement transclusion processing #91 (with Transclusion, mostly #103) by implementing DocBook Transclusions.
• CSS improvements for revisionhistory tables
• Improved handling of db:coref
