Update framework and app pages

[wdower]

• add graphics to break up framework pages visually
• add "integrations," "downloads/how to get it" sections for apps

Can we change the width of the framework pages to be the same as the other pages? It looks wider right now. If it's outside the scope of this issue, I can write another one.

Edit: I see that the framework width matches the width of paragraph text on the app pages. Perhaps it is best to either leave them as matching or change both to match the front page.

Thank you for bringing this up. I'll talk with Will tomorrow about this.

I'm not concerned with the homepage and the framework/app pages having separate widths.
