Implemented pullquoteleft functionality
Edited .themes/classic/sass/base/_typography.scss via GitHub
Updated pullquote.rb to use a vernacular similar to the image tag.
Renamed has-pullquote and has-pullquoteleft classes to pullquote-right and pullquote-left (I suppose a less stylistic naming convention might pullquote-default and pullquote-alternate.)
Added class='citation' to blockquotes generated by the blockquote plugin to differentiate their style from the style of an html or markdown blockquote.
Separated citation style from the general blockquote style. The general blockquote style is great for nesting and indentation, while the citation is excellent for quote attribution.
Reverted previous commit to separate that change to a different pull request.
