Changed kitten data to be more robust
Fixed response set to use latest kitten data object
Added migration to update existing kitten data
Added tests for kitten data model, minor refactor to kitten data model
Merge branch 'master' of github.com:theodi/open-data-certificate into kitten-data-improvements

Conflicts:
	db/schema.rb
Add counts to models

Because DRY
Rename certificate dump methods
Genericise upload method
Put directory into a method for reuse
Require CSV class
First pass at stats generation
Add counts of certificate levels
Forgot to rename methods in tests
Only get published certificates per level
Typo with rake tasks
automatically updated dependencies
Pin Devise version down
More naming changes

Naming things is hard
Tests for statistics
Remove rake tasks
