Add footer to webpage

[kara-mela]

Motivation

A footer give a webpage a visual conclusion. The PaNET webpages currently do not have a footer and we should change that.

Modification

Added content to footer.html, added designs by creating footer.css and including it in the head of the html document.

Result

A footer has been added.

I like the footer, it makes the website look more professional. From what I'm qualified to judge, I agree with the content.

The situation with the two conflicting scroll bars could maybe be resolved by removing the max-height and overflow-y properties from the #scope-sidebar in custom.css. Additionally, I left some very small comments.

Suggested change

	padding: 0px 48px 0px 48px;
	padding: 0px 0px 0px 48px;

My personal preference would be to remove the right padding, e.g. so that the Photon and Neutron Open Science Cluster link no longer has a line break.

To me, it looks like this with 48px right padding:

Suggested change

	<div class="footer">
	<footer class="footer">

Small nitpick: Could use footer instead of div. This is aligned with the current header and better for accessibility.

Thanks for your comments, @eilmiv. I updated the code accordingly.

@kara-mela just a ping in case you forgot about the scroll bars. (feel free to ignore this comment in case it was an active decision to not address this)

Thanks for bringing the scroll bars up again. They are annoying me and I already tried to get rid of them but failed. Your solution works! Thanks!

Unfortunately, your approvals still don't count. I will ask Paul to inspect this.
