* Add search with elasticlunr.js
This commit adds search functionality to mdBook, based on work done by @phaiax. The in-browser search code uses elasticlunr.js to execute the search, using an index generated at book build time by elasticlunr-rs.
* Add generator comment
Someone on Reddit was wondering how the rust book was generated and said they checked the source. Thought I'd put this here. Might be a good idea to have a little footer "made with mdBook", but this'll do for now.
* Remove search/editor file override behavior
* Use for loop for book iterator
* Improve HTML regex
* Fix search CORS in file URIs
* Use ammonia to sanitize HTML
* Filter html5ever log messages
* feat(theme/index): Assume the sidebar is initially visible
In case the inline script does not execute, the fallback is to show the sidebar.
* feat(theme/index): Hide sidebar toggle and theme selector buttons when JavaScript is disabled
Makes no sense to show them in this case since they do not work.
* fix(theme/book/themes): Check for control keys in event listener
* fix(theme/index): Menu role for theme selector
* fix(theme/book/themes): Handle focus when toggling theme list
* feat(theme/book/themes): Handle ArrowUp, ArrowDown, Home and End
> A position fixed left navigation bar does not want to hand off scrolling to the document because a scroll gesture performed on the navigation bar is almost never meant to scroll the document. In this case, the author can use contain on the sidebar to prevent scrolling from being chained to the parent document element.

Tested this on macOS with VoiceOver, and it does not pick up the title as the text of the button. Kind of makes sense, since title and aria-label are not the same. This will make sure that the buttons and links are labeled properly.
Advantages:
- Easier to reason about
- Can easily disable some modules when debugging
- Shared dependencies are explicit (playpen_text)
- Enables some fancier things later one (e.g. run `codeSnippets` slightly later, to avoid blocking the page)
I'm aware that `codeSnippets` should be split into the highlighter and the editor, but I'm not sure I understand exactly how they interact so I've left it as it is for now.

* Added example output
* Added a config section to the backends tutorial
* Finished off the backends tutorial
* Made sure travis checks mdbook-wordcount
* Fixed the broken link at in the user guide

* Added a conclusion
* Went through and documented a lot of stuff
* Added a preprocessors chapter and updated For Developers
* feat(theme/stylus/menu): Make sticky
* feat(theme/stylus/menu): Faint bottom border
* feat(theme/book): Auto hide menu when scrolling down
* feat(theme/stylus/menu): Don't hide title
* feat(theme/stylus/menu): Only show bottom border when sticky
* fix(theme/stylus/menu): Don't hide when sidebar is expanded
* feat(theme/book): Show menu bar on hover
* fix(theme/index): Use nav element for Table of Content
* fix(renderer/html_handlebars/helpers/toc): Use ol instead of ul
Chapters and sections are ordered, so we should use the appropriate HTML tag.
* fix(renderer/html_handlebars/helpers/toc): Hide section number from screen readers
Screen readers have this functionality build-in, no need to present this. Ideally, this should not even be in the DOM tree, since the numbers can be shown by using CSS.
* fix(theme/index): Remove tabIndex="-1" from .page
Divs are not focusable by default
* fix(theme): Make sidebar accessible
Using aria-hidden (together with tabIndex) takes the links out of the tab order.

* fix(theme/index): Wrap content inside main tag
The main tag helps users skip additional content on the page.
* fix(theme/book): Don't focus .page on page load
The main content is identified by the main tag, not by auto-focusing it on page load.
* fix(theme/index): Make page controls accessible
* fix: Make theme selector accessible
- Use ul and li (since it is a list)
- Add aria-expanded and aria-haspopup to the toggle button
- Use button instead of div (buttons are accessible by default)
- Handle Esc key (close popup)
- Adjust CSS to keep same visual style
* fix(theme/stylus/sidebar): Make link clickable area wider
Links now expand to fill the entire row.
* fix(theme): Wrap header buttons and improve animation performance
Previously, the header had a fixed height, which meant that sometimes the print button was not visible. Animating the left property is expensive, which lead to laggy animations - transform is much cheaper and has the same effect.
* fix(theme/stylus/theme-popup): Theme button inherits color
Bug introduced while making the popup accessible
* fix(theme/book): Handle edge case when toggling sidebar
Bug introduced when switching from animating left to using transform.
* Added a mechanism for creating alternate backends
* Added a CmdRenderer and the ability to have multiple renderers

* Added a couple methods to RenderContext
* Converted RenderContext.version to a String
* Made sure all alternate renderers are invoked as `mdbook-*`
* Factored out the logic for determining which renderer to use
* Added tests for renderer detection
* Made it so `mdbook test` works on the book-example again
* Updated the "For Developers" docs
* Removed `[output.epub]` from the example book's book.toml
* Added a bit more info on how backends should work
