data sorting needed a new variable to differentiate between index page
rendering and standard page rendering, so that was added to the return
as well as updating the render script to include the variable that
wasn't being added for tags
also updated the git ignore file to ignore global images that are not
used by the base system. the script theme folder needs to be ignore as
well as that is going to updated by the theme itself for front end
coding and not used by the system
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
