added support for thumbnails/featured image to movements and WODs
added event and difficulty level icon to movement index page template
added WODs on front page, need to style WODs
initial checkin of single_movement.php to create a template for how each
individual movement page looks
renamed, dash instead of underscore seems to be needed for wordpress to
actually use the template automagically
added CSS calendar date icon for WODs and tweaking column layout so that
2 columns are used, even on mobile
further tweaks to the calendar icons on front page now display month
date and year and icon is much smaller to allow more room for WOD panel
added placeholder legend for movements
