This commit adds a bit of string wrangling to avoid the keys in our javascript source file also being transformed. Additionally, whilst looking at this we decided that Maps are a better dictionary than javascript objects, so we moved to use those here also (but this doesn't affect the issue)
* Configure ember-auto-import so we can use a stricter CSP
* Create a fake filesystem using JSON to avoid inline scripts in index
We used to have inline scripts in index.html in order to support embers
filepath fingerprinting and our configurable rootURL.
Instead of using inline scripts we use application/json plus a JSON blob
to create a fake filesystem JSON blob/hash/map to hold all of the
rootURL'ed fingerprinted file paths which we can then retrive later in
non-inline scripts.
We move our inlined polyfills script into the init.js external script,
and we move the CodeMirror syntax highlighting configuration inline
script into the main app itself - into the already existing CodeMirror
initializer (this has been moved so we can lookup a service located
document using ember's DI container)
* Set a strict-ish CSP policy during development
