Style the initial footer

[lili2311]

• we have the initial footer HTML but it needs styling

• Example Desktop:
  

• On mobile, everything will look the same but the Right reserved paragraph perhaps on it's own line.

• The footer should have a .footer class and all footer related code within this

• The footer should be it's own sass partial

• The footer HTML should be added to the base template in Django

• Footer should be at the bottom of the screen when there is not enough content. If there is enough content then move it at the very bottom of content. Here is how to do it: http://matthewjamestaylor.com/blog/keeping-footers-at-the-bottom-of-the-page
