Title: Polymorphic embedded picture objects

# Why?

* We're hitting a point where lots of 'things' need pictures

# What Changed?

* Added a `Picture` model that can be embedded into anything polymorphicly.

# What's Next?

* Figure out some sane defaults for photo sizes.

This is incomplete, but stable and mergable.
