Redesigned User-Friendly 404 Page

Static Standalone 404 Page - Would Not Affect Load Time.

Seems like there's a lot of extraneous code here- why do we need FontAwesome for just one GitHub icon?? Why is Roboto in assets? What is "site pages" in 404?

Also, stop squashing your commits, it's better to have lots of smaller commits rather than one or two massive commits.

1. I will use a cdn for fontawesome too.

2. Roboto is in assets because it's needed by fonts.css, which main.css have a dependency on.

3. I added a comment just above "Site Pages". <!--Uncomment Above To Enable Menu-->. It's shown if you uncomment those lines.

4. Squashing small commits to prevent spam in the commit log. More insight could be found on https://softwareengineering.stackexchange.com/questions/263164/why-squash-git-commits-for-pull-requests

Sorry, I wasn't being clear, it was late and i was sleepy :PPP

Anyways, I'll make a few things clearer:

1. Great 👍
2. Since Materialize already uses the Roboto font from their server, you can copy that and it won't require any more loading times or file bloating. https://cdnjs.cloudflare.com/ajax/libs/materialize/0.98.2/fonts/roboto/Roboto-Regular.woff2
3. Sorry I didn't catch that, I was on phone and didn't look at it closely enough. That's great 👍
4. Squashes like the one you did are fine, it's just that if you are doing lots of things that are unrelated, don't squash them. Several commits to the same file may be squashed. (@EnumC we should write a guide about when to squash in CONTRIBUTING)

Final very important thing:
Angular by default does not actually use a 404 page. I'll make a commit to the branch to make it do so.

TL;DR I'll make sure the 404 redirects properly; everything seems fine except for the duplicate Roboto.
