Global Header

[jonwinton]

Is your feature request related to a problem? Please describe.

We need a simple, global header

Describe the solution you'd like

The header should be able to:

• Render a logo
  • Logo should link to the homepage
• Display a tagline
• Display links to social media sites
• The social links should have to different behaviors:
  • On section front pages the links should be able to be configured to go to a specific page (facebook page, twitter profile, etc)
  • On a content page (article or otherwise) they should be share links for the current url you're on

Describe alternatives you've considered

Idea: it might be good if a user can paste and svg into a field rather than requiring a file be on the filesystem.
