Merge pull request #75 from jeremyBass/master

change to keep cropped unaltered
Add background color to #glue
Quick fix of cropped spine CSS
Add cropped test to demo

Results from this often aren’t pretty when the page isn’t designed for
it, but for testing, it’s helpful.
Remove spine.html and demo.html from grunt prod
Set #spine height to allow for mouse events
Remove min-height when toggling to cropped
Set .cropped #spine height

I thought I could avoid this redundancy, but with the spine extending
the window’s full height it interferes with mouse events even though
invisible.
Add .fifteenths default container

This needs to be built out exhaustively asap
Another attempt at modify fifteenths max-width
Make social channel iconography available looseleaf
Add before to looseleaf social channels
Add before to looseleaf social channels
Work on social channel specificity/weight
Work on social channel icons
Work on social channel icons
Eliminate double classes

Hat tip, @wjbonner.
spine.html should reference spine.min.css
Folio widths should apply to all behaviors?
Same verse
