Make improvements to the YARD layout

* Adjust padding/margin around and inside of blockquotes
* Use ems for p margin
* Since we will be adding a custom file whose title is camel-case,
  make two changes to the header:
  * Drop "File:" in the header for files
  * Change styles for header and search to use standard case instead
    of all caps, and drop letter spacing
* Make footer smaller and more human readable
