Don't flag whitespace at EOL as errors in markdown

Add a .gitattributes file specifying git shouldn't highlight whitespace
at end of line as an error.  I have vim configured to include the `w`
flag in the `formatoptions` setting which uses trailing whitespace on a
line to indicate that the paragraph continues onto the next line.  This
allows it to reflow paragraphs automatically with less likelihood of
merging lines that where the break is important.
Use spaces to indent style.scss

My .editorconfig file specifies that spaces are being used, so adjust
the style.scss file to match that.
Add "Fork me on GitHub" ribbon

Add a ribbon pointing to the GitHub repo using CSS generated with

Convert CSS for "Fork me" ribbon to SCSS

The initial CSS source for the "Fork me" ribbon had a lot of redundancy,
reduce that by converting it to use SCSS enhancements.
