it can't be validate if path parameters not defined

[winterbesos]

/some/api/{param}:

if this param is not be defined. the command swagger-cli validate api.yaml can't throw any errors.

Also if the parameter is defined but not in: header it won't fail.

Note: to all - stand by - there will be a Pull Request soon.

Basically I think the command line tool could do with the validation in the editor
