Data model for beer details
This link was kinda confusing
Prototype of angular app
Use djangorestframework
Better spacing on link
Initial REST API for JS
Merge branch 'add-current-column' into bjcp-specifications

Conflicts:
	homebrewit/contest/views.py
Fix broken tests
Filter beers by year
Replace this method with a relation
Use the manager method
Include beer_details in the JSON
BeerDetails belong to subcategories
Passing current year into the controller
Migrate subcategories into beer_styles

Basically make beer_styles self-referential so categories and
subcategories are in the same table
Merge branch 'make-subcategories-categories' into bjcp-specifications

Conflicts:
	homebrewit/contest/admin.py
	homebrewit/contest/models.py
Fixing the model merges
Some model manager helpers
Semi-working dropdown
Conditional for whether a menu item is clickable
