Fix FontAwesome directory missing from Github Pages sites

[mattico]

Fixes #693

https://help.github.com/articles/files-that-start-with-an-underscore-are-missing/

By default, Jekyll does not build any files or directories that

• are hidden or used for backup (indicated by names that start with . or #, or that end with ~);
• contain site content (indicated by names that start with _); or
• are excluded in the site configuration.

To me this doesn't indicate that the not-built files won't end up on the target site, but that is actually the case: https://stackoverflow.com/questions/6397780

I verified that this build does create a working Github Pages site.

I noticed this behavior recently too.
Thanks for the fix!

Is there any chance we can get a new crates.io release? This is affecting quite a number of books.

@Michael-F-Bryan usually does that, but he's been busy recently.

Unfortunately I've been a bit busy with work recently and not had time for my personal projects, but I'll make another release around lunch time.

As a side note, I'd hate for mdbook to be neglected on my account. @mattico , you may want to ask @steveklabnik about getting commit rights for the repository so you can merge PRs (if you can't already).

Version 0.1.8 is on crates.io 🎉
