Code review comment for lp:~joetalbott/utah/utah-dev_doc-updates

Since you're today on vacation and the documentation should be up-to-date in UDS,
I've merged the changes and made a small set of changes:

- FAQ section moved to its own file (faq.rst)
- Fixed typo (make is possible -> make it possible)
- Reformatted paragraphs with long lines to fixed width
- Changed some single quotes that were still there (from other commits) to
  double back quotes.
