Reorganization of the Theme Settings

I think it would be nice to organize and simplify the theme settings a little bit so they are easier to navigate.

This is what I have come up with so far, but it's just an idea.

Thoughts?

Theme Settings (collapsed):

Theme Settings (expanded):

Text Inputs for theme links

Since you cannot add links to the theme settings, I have used text inputs which can be copy/pasted into a browser. And while they could be overwritten, there is always a button to reset the value back to the default link.

Unit Hints for Number Input Fields

@pryley Style Settings has released an info-text field that supports markdown so I'll be changing links to match that format. Just letting you know in advance.
