conversion of markdown files to html works fine, but the coresponding
css, js and image assets were not being moved, so the class responsible
for moving them was edited so theme assets are moved to their
appropriate directories when the site is published.
also made some css and image edits, and removed a legacy css files that
were no longer in use
theme controller was getting top heavy, so an asset service class was
plugged in to handle moving assets around for theme testing and
eventually to production when HTML rendering is set up
