Mixins not defined, Shadowbox not defined

[joseph-devito]

I feel like both of these are probably quick solutions but rather than write my own I figured Id ask you first:

1. the "bp" mixin and variables arent defined, what are you using for those? (again I know I could define the mixin and use my own values for the variables)

2. line 1 of global.js "Shadowbox" is not defined... is there a JS library that I need in order for shadowbox to work? (I googled but there were a few and I want to make sure I grab the right one)
