Shifter error shows as [object Object]

[redonkulus]

If shifter cannot find a file or some other issue occurs it is displayed as:

shifter [err] css: [object Object]

The error object is passed into the log method assuming its a string, which will just print out the above message. I tried using error.toString() and error.message but neither displayed the error. Perhaps we just output log.err(err) to at least see the error.
