Exceptions should handle ansi colors

[ayalash]

Example for exception message:

...
error: Found argument '--ignore-dir' which wasn't expected, or isn't valid in this context
	Did you mean �[32m--�[0m�[32mignored-dirs�[0m?

USAGE:
... For more information try --help ...

@vmalloc I'm not sure if we want to ignore the ansi colors or display them as colored text. What do you think?

[vmalloc]

It would be nice to show them correctly, of course...
