- `.get('key')` would error because it was incorrectly expecting the internal content object to contain `{key, value}` objects
- changed `.getAll()` to return a shallow copy of the internal content object so we don't leak references that can result in unexpected changes to the cache content
- changed the internal content object naming to `_content` to highlight that it's an internal/private implementation detail rather than a public API
no issue
- the `.browse()` call to fetch themes was not structured to filter out themes correctly so it was fetching all theme settings rather than only settings related to the current theme
no issue
- `for .. of` loop contained a `return` rather than a `continue` so the whole function was being exited with an unexpected `undefined` return value after the first loop where an unknown setting is removed

- receives settings array as provided by through Ghost's API
- errors if a provided setting key does not already exist in the database (settings are only created when syncing with a theme)
- errors if a provided select setting value does not match the theme-provided options
- providing there were no errors, updates each value in the database if it's changed along with the internal cache of full setting objects and the public key/value cache
- returns the same list of settings as `.listSettings()` for API consistency
refs https://github.com/TryGhost/Team/issues/1070
- if the cache is repopulated, keys that already existed in the cache but that don't exist in the new group of settings were left in the cache
- added a `.clear()` method that removes all items from the cache and call it when populating so the cache only contains what it was last populated with
- deletes properties on the internal content object so that references aren't lost

- return re-fetched settings after sync so they can be used in later activation steps
- added internal `activeThemeSettings` cache that stores full setting data along with saved values for use in API output
- added `listSettings()` that converts internal cache object into a settings array that matches API format
refs https://github.com/TryGhost/Team/issues/1070
- having a dependency on a model in the cache service meant that Ghost had to know about that and pre-initialize the cache during boot, even though that didn't actually do anything except create a cache instance
- by making the cache a simple key/value store able to be populated from the cache settings service when a theme is activated it means that Ghost doesn't need to perform any extra initialization when the cache is initialized via `require`
refs https://github.com/TryGhost/Team/issues/1070
- added `bread` util that acts as a wrapper for the provided model, if we have any business functionality needed when settings are added/removed then it will go here
- added primary "server" service that handles syncing of custom theme data extracted from a theme with the settings that are in the database and exported as "Service". Syncing rules on theme activation:
- if a new setting is seen, create it with the default value
- if a setting has it's type changed, remove it and create a new setting with the default value
- if a select setting's value is not a valid option, reset it to the default value
- added shared "frontend/server" service that exposes an in-memory cache of key/value pairs for the currently active theme
