v1.4.0

Added

• Generic.PHP.ForbiddenFunctions config: forbids
  intval(), floatval(), strval(), and boolval().
  Use (int), (float), (string), and (bool) casts
  instead.
• Apermo.Functions.ForbiddenNestedClosure sniff: warns
  when closures or arrow functions are nested inside other
  closures or arrow functions. Extract inner callbacks to
  named functions instead.
