PageSpeed Insights performance issues

[ElliotFriend]

There are several different ways that we ought to improve performance, as revealed by Google's PageSpeed Insights. Here are the top issues that we're showing:

Should Fix

• [ ] Eliminate render-blocking JavaScript and CSS in above-the-fold content
  • [ ] Remove render-blocking JavaScript
  • [ ] Optimize CSS Delivery
• [ ] Optimize Images (Mostly compressing, some resizing for mobile?)

  Consider Fixing

• [ ] Minify JavaScript
• [ ] Leverage browser caching (For the Facebook like button and the Google Analytics tracking code)
• [ ] Minify HTML

  Mobile User Experience

• [ ] Size tap targets appropriately (FAQs and Contact Us Links in the header are too close)

Eliminate render-blocking JavaScript and CSS

There are way more CSS files (12) that are listed, than there are JavaScript files (5). We should probably focus there.

The contrib/imageapi_optimize module has some real promise. The catch is that we would need to re-save the images we want to optimize, because that's the time when they are optimized.

For all of the Slideshow images, we'll need to run them through TinyJPG/PNG. It's been quite a helpful find for me.
