#23 Exit code of failed validations should be non-zero

[Slaven Rezic]

If the command line tool fails to validate a yaml file, then — in good Unix tradition — the exit code should be non-zero. So the kwalify tool could be easily be used in shell scripts and makefiles. Currently the exit code is always zero.

This is what I currently observe:

$ kwalify -f schema.yaml failing_data_file.yaml ; echo $?                          
_etc/hosts-kwalify.yaml#0: INVALID
...
0

Note that the equivalent perl utility (pkwalify in the CPAN module Kwalify.pm) does it right.
