Show recent photos on the home page, linking to the view photo page.

Issues:
* There are no thumbnails images in the export. Using browser-resized originals works for now, but slows the page down significantly and has inconsistant dimensions
* The IndexView renders photo previews in a loop, this should be a sub view
Move bootstrap into it's own component dir in preparation of adding our own css and considering managing CSS dependencies with bower, like JS
Use bootstrap responsive - no real reason not to
Initial app css, style photo list items
Add a sub-view that renders individual list items
