0.1.2

I know, I know. Bad form to release another so quickly. Some glaring omissions and issues necessitated it though:

• Add: App-wide - Bundled sans font. Because some OSes haven't learned the value of including weights between 400 and 700.
• Add: Piece Library - List view - Practice status pills to pill row
• Add: Upload flow - Cancel buttons! Seriously, didn't even realize. My bad.
• Fix: App-wide - Lightbox wasn't on top of some fields
• Fix: Edit Piece modal - Page preview wrong size, reordered fields to flow better
• Fix: Backend - PDF thumb generation used mediabox instead of cropbox
• Fix: Footer - Rebalanced the footer

Promise I'll be more spaced out going forward.
