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
