Sam Saffron 30990006a9 DEV: enable frozen string literal on all files
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.

Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging

# frozen_string_literal: true
# This contains two patches to make sprockets more tolerable in dev
#
# 1. Stop computing asset paths which triggers sprockets to do mountains of work
# All our assets in dev are in the /assets folder anyway
#
# 2. Stop using a concatenator that does tons of work checking for semicolons when
# when rebuilding an asset
