Fix footer width calculations

-The footer was being resized at the wrong width breakpoints because of an issue with determining the current width of the screen. If you had previously fine-tuned your page_footer.footer_height_xxx and page_footer.social_link_percent_height_xxx options, they may need to be readjusted to account for the new proper width breakpoints after this fix is applied
