Default Rails primary_key and references to string (monkey patch)

	# By default, rails expects id's to be a integer
	# In our app, we store id's as strings.
	#
	# To make our life easier, instead of always having to remember this
	# and explicitly telling rails the id is a string, I'm going to monkey
	# patch some migrations and AR methods.
