Ghost/core/server/helpers/pagination.js
Katharina Irrgang d81bc91bd2 Error creation (#7477)
refs #7116, refs #2001

- Changes the way Ghost errors are implemented to benefit from proper inheritance
- Moves all error definitions into a single file
- Changes the error constructor to take an options object, rather than needing the arguments to be passed in the correct order.
- Provides a wrapper so that any errors that haven't already been converted to GhostErrors get converted before they are displayed.

Summary of changes:

* 🐛  set NODE_ENV in config handler
*   add GhostError implementation (core/server/errors.js)
  - register all errors in one file
  - inheritance from GhostError
  - option pattern
* 🔥  remove all error files
*   wrap all errors into GhostError in case of HTTP
* 🎨  adaptions
  - option pattern for errors
  - use GhostError when needed
* 🎨  revert debug deletion and add TODO for error id's
