WSH executable throws errors while loading files

[scottgonzalez]

While working on #359, we ran into problems with the WSH script. I don't have an environment to test in, so I asked @dmethvin to test. His problems can be found in these IRC logs

The WSH script attempts to load the .csslintrc file but doesn't catch the error that results if the file isn't there. The wiki indicates the settings file is optional.

Looking at the node.js equivalent it seems that returning an empty string an a missing file is the desired behavior. I can do a separate PR on that.

@dmethvin - did you submit a pull request for this?

[dmethvin]

Whoops, I did not. Just did #376.

[dmethvin]

oh darn, sorry.

[stubbornella]

Thanks!
