Better bigimg support

Add support for bigimg's on the front page, multiple images that rotate
on both the front page and regular pages and posts, also added test
images and a sample to demonstrate the functionality and how to specify
bigimg's.

 Under what circumstances should we step off a path? When is it essential that we finish what we start? If I bought a bag of peanuts and had an allergic reaction, no one would fault me if I threw it out. If I ended a relationship with a woman who hit me, no one would say that I had a commitment problem. But if I walk away from a seemingly secure route because my soul has other ideas, I am a flake?

+The image banners at the top of the page are refered to as "bigimg" in this theme. They are optional, and one more more can be specified. If more than one is specified, the images rotate every 10 seconds. In the front matter, bigimgs are specified using an array of hashes.
+
+<!--more-->
+
+A single bigimg can be specified in the front matter by the following YAML:
+```
+bigimg: [{src: "/img/triangle.jpg", desc: "Triangle"}]
+```
+
+Multiple bigimgs can be specified in the front matter by the following YAML:
+```
+bigimg: [{src: "/img/triangle.jpg", desc: "Triangle"}, {src: "/img/sphere.jpg", desc: "Sphere"}, {src: "/img/hexagon.jpg", desc: "Hexagon"}]
+```
+
+Also note that the description field is optional, and images could instead be specified by:
+```
+bigimg: [{src: "/img/triangle.jpg"}, {src: "/img/sphere.jpg"}, {src: "/img/hexagon.jpg"}]
+```
