Ghost/core/frontend/helpers/date.js
Hannah Wolfe fd20f90cca
Divided f/e proxy into true proxy + rendering service
- The original intention of the proxy was to collect up all the requires in our helpers into one place
- This has since been expanded and used in more places, in more ways
- In hindsight there are now multiple different types of requires in the proxy:
   - One: true frontend rendering framework requires (stuff from deep inside theme-engine)
   - Two: data manipulation/sdk stuff, belongs to the frontend, ways to process API data
   - Three: actual core stuff from Ghost, that we wish wasn't here / needs to be passed in a controlled way
- This commit pulls out One into a new rendering service, so at least that stuff is managed independently
- This draws the lines clearly between what's internal to the frontend and what isn't
- It also highlights that the theme-engine needs to be divided up / refactored so that we don't have these deep requires
