From php.net/exception.getcode
> Returns the exception code as integer in Exception but possibly as other type in Exception descendants (for example as string in PDOException).
This statement does not serve a purpose anymore.
In a long forgotten world it indicated the main version number of PHP which the code in the file was compatible to.

But since PHP 5.1 and later this is only marginally true.
Thus I propose to remove it from CakePHP.
Uncaught exceptions on the console would result in exit code 0.
This is not helpful in *nix scripting.
- Update the ConsoleErrorHandler to not inherit from the web error handler.
- Make ErrorHandler::_mapErrorCode() public as it isn't overly private.
- Make ConsoleErrorHandler methods instance methods so mocking can be done.
- Add a _stop method to correctly exit.
- Update tests.
