Fix whitespace in install and integration docs

Many code blocks are 4spaced, and they render in GitLab
without coloring as a result, even though they are
fenced with a language label. If in a list, other items
will render as being in a code block too, even if not
meant to. This fixes all these issues, and cleans up
minor white space issues in install and integration docs

 On the sign in page, there should now be an UltraAuth icon below the regular sign in form.
 Click the icon to begin the authentication process. UltraAuth will ask the user to sign in and authorize the GitLab application.
