CLI error should be rendered directly to Terminal

[janbarasek]

I think CLI errors should be rendered directly to Terminal for better debug.

Concept:

Inspired by: https://github.com/baraja-core/nette-symfony-console/blob/master/src/Console.php#L67

Thanks.

duplicated to #486 ?

[janbarasek]

A little yes. I would also add the file name and line number (for easy copying) and snippet code where the exception was thrown.

What do you think?

So it's about dumping a snippet of source code in debug mode? Yeah, that can be useful.

[janbarasek]

Yes, it will. I can try implement it.
