Objects passed to the context output methods aren't serialized

[jkells]

It's common to call context.succeed context.error and context.done with an object instead of a string.

The lambda invoke task fails to output them, instead just printing the following

Success!  Message:
------------------
[object Object]

I think the output objects should be serialized so you get some sane output.

According to the AWS Lambda documentation the result provided must be JSON.stringify compatible so 👍 for #55

Thanks for reporting this issue.

It should be resolved by this pull request in the next release: f544e42
