General revisions to (hopefully) make the documentation
easier to understand and more comprehensive.
Revise "Strange EOF error" troubleshooting page to say that
a fix is in place for the upcoming Hugo v0.13.
Also add more external links, and cute icons from Font Awesome.
- Correct some typos
- Add backticks and commas where necessary
- Use fenced code blocks specifying "bash" as the language
to avoid weird highlighting
- Place commas outside of quotation marks surroundingn codes
to avoid possible confusion
- Suggest users to use the discussion forum rather than the
mailing list
