- switch `jscs` and `jshint` inline config to `eslint` config
- fix eslint errors, predominantly in tests where the config now the main app config more closely
closes https://github.com/TryGhost/Ghost/issues/6974
- update "change password" fields/process to use inline validations
- remove `notifications.showErrors` and update all uses of it to `showAPIError`
- display multiple API errors as alerts rather than toaster notifications
- refactor `notifications.showAPIError`
- remove `notifications.showErrors`, use a loop in `showAPIError` instead
- properly determine the message from `AjaxError` or `AdapterError` objects
- determine a unique key if possible so that we don't lose multiple different alerts
- add `ServerUnreachable` error for when we get a status code of 0 (eg, when the ghost service has been shut down)
- simplify error messages for our custom ajax errors
no issue
