There is no /slurm page, this was missed in the new style conversion.

This partially reverts commit a309f77c.

It accidentally removed the menu function on mobile devices.

Bug 4128

Page needs to display properly even if the CDN gets rid of this, or
for machines with no internet connectivity.

Fix a few minor style issues, and remove some unused javascript.

Change header and footer over to new design, switch around the css
files, and adjust the build system to match.

Design by Grant Zabriskie.

Switch a few SLURM mentions for Slurm as well.
