schedule.html
-deleted no-show
schedule.js
-now changing available shift number in db instead of script-side, this is the cause for the speediness reloading in shift circles

z.css
-deleted and filed away into header.css
header.css
-added in styles from z
-added a media query so header would not be so broken around 300px width
application.css
-deleted import for z
schedule.css
-deleted un-used selector
-added media-query styles so schedule inner nav would statically pop down at around 300pxs isn
