* Updated phpdoc so it has \Throwable
- `abstract protected function renderException($exception);` is extended in web/ErrorHandler to also have `\Error`.
- `public static function convertExceptionToError($exception)` is called from widgets/ActiveField.php with
```
/**
* PHP magic method that returns the string representation of this object.
* @return string the string representation of this object.
*/
public function __toString()
{
// __toString cannot throw exception
// use trigger_error to bypass this limitation
try {
return $this->render();
} catch (\Exception $e) {
ErrorHandler::convertExceptionToError($e);
return '';
} catch (\Throwable $e) {
ErrorHandler::convertExceptionToError($e);
return '';
}
}
```
* Add \Throwable to phpdoc in response.php
The ErrorHandler has been updated in phpdoc to have throwable, this complets that change.
