Staging icon tweaks

Hi Donna Stuart,

Would like to merge some changes I did in my staging_icon-tweaks branch into gh-pages branch.

In these commits I moved the positioning of our Github and rise links at the bottom of all the templates. I also cleaned up some comments and inline styles and deleted the menuboard template which I will be completing redoing.

Let me know if anything looks odd.
I will work on squashing it into 1 commit next PR.

Thanks,
Mat
