0.17.0

I hadn't made a proper release in a long time, so I thought it was better not to postpone anymore. Besides updating a few dependencies, 0.17.0 removes a few feature that were not really maintained anymore, such as a libreoffice writer export.

* Try to get rid of technical debt, including removing features that were half baked and not really useful.
  * Remove proofread options.
  * Remove ODT renderer.
  * Replace mustache for templates by [upon](https://crates.io/crates/upon)
  * Use rust-i18n for internationalization instead of hackish (and unmaintained) crowbook-intl
* HTML:
  * When hovering a mouse hover a footnote, display its content to the side of the page.
* LaTeX:
   * Add `tex.cover` option to embed the cover image in the PDF file

  performances drawbacks but allows for a few more features:
  • Description lists
  • Strikethrough
  • Task items
• New option:
  • crowbook.files_mean_chapters allow to enforce that each files
    means a chapter break or to make sure that it doesn't (by default,
    only true for numbered chapters).
• Fallback on Rust zip library when there is no zip command.
• By default, don't add an empty chapter title for non numbered
  "chapters" that don't contain a title.
• Now uses reqwest instead of hyper to connect to languagetool/grammalecte.
• hyphenation dependency is now optional.
• Dependencies update.
• Fix type deduction issues for new rustc compliler

  --verbose option (if support for advanced statistics is compiled)

  rendering.part

  • User interface is quite fancier, with progress bars and all

    in your terminal)

0.13.0

• Breaking changes:
  • The template.tex template was quite modified. Crowbook now
    uses custom command for most markdown elements, defined in the
    template. This allow an user to redefine the way the book is
    rendered without having to modify Crowbook itself. Unfortunately,
    as tex templates for previous Crowbook versions won't work anymore.
  • the resources.files option is now a YAML list of strings, instead of a
    comma-seprated string.
• Add support for grammalecte grammar checker.
• crowbook command takes a new argument, -S or --stats which
  displays stats on the book (currently, words and characters count).
• Interactive fiction:
  • Added conditional blocks.
• Options:
  • output.xxx options can now take the "auto" value, which will infer the
    output file name based on the book file name.
  • output is a new option that can specify a series of format to
    render, with default output file name.
  • proofread.grammalecte and proofread.grammalecte.port allow
    respectively to enable grammar checking with Grammalecte and
    (optionnally) to specify the port to connect.
  • tex.margin.left, tex.margin.right, tex.margin.bottom and
    tex.margin.top are new options that allow to specify margins
    for LaTeX/PDF outputs.
  • tex.paper_size was renamed tex.paper_size.
• HTML:
  • Add JSON-LD structured data to the book's HTML files.
• Bugfixes:
  • LaTeX: fix rendering of part/chapter (part previously displayed as
    chapter and its first chapter as part)
  • EPUB:
    • Fix .rule so it is centered despite KOBO CSS injection.
  • Fix resources/images inclusion when they are symlinks to the
    actual file.
