no issue
- pass `srcsets` value through to mobiledoc renderer
- it will stop adding `srcset` attributes to images when explicitly set to `false`
- adds `reload()` method to `mobiledocLib` so that memoized instances of the renderer can be reset during tests that change config values
no issue
- adds a set of hardcoded "content image sizes" to the base config
- adjusts `handle-image-sizes` middleware to always allow the hardcoded content image sizes to be genreated
- updates `@tryghost/kg-card-factory` to allow passthrough of options to card renderers
- updates `@tryghost/kg-default-cards` to add `srcset` output for image and gallery cards
* moved `server/config` to `shared/config`
* updated config import paths in server to use shared
* updated config import paths in frontend to use shared
* updated config import paths in test to use shared
* updated config import paths in root to use shared
* trigger regression tests
* of course the rebase broke tests
