Add ability to customize the site logo from Tina

[spbyrne]

Currently to customize the site logo you’ll need to modify two files: src/components/header.js and content/images/icon.png. The header logo is a styled-icon which allows for easy theming.

Ideally you'd be able to select from a preset selection of styled icons with the ability to upload a custom logo. Additionally, it would be great if you didn't have to also provide a .png image for the site icon as it's not theme-able.

I think a custom Tina input would be a good choice for an icon selector.

It would be nice as well to be able to set logo to false.
I do have a website on which I don't need to display that.

This is the website: https://parenthood.blog

That's a great point! I can certainly add that feature.

To do this now you'll have to modify src/components/header.js. Basically just remove <Coffee /> from it:

<SiteTitle>
  <SiteLink to="/">
    <Coffee />
    {siteTitle}
  </SiteLink>
</SiteTitle>

Additionally you'll have to modify (but not delete) content/images/icon.png.
