Issue:414 - Fix Individual deploy of functions

[ndanielsen]

Fixes #414

I created the mentioned issue awhile back.

It seems that the issue is that the serverless framework is no longer setting and passing on the package or artifact (zip file) location (ie func.package.artifact) for the function.

Also the injectAllRequirements is no longer passing on the funcArtifact, instead it is passed an undefined object.

This is more of a patch and I'm not sure if this will break other things. Individual deploys of function and deploying the entire service work for me on my Mac with:

    pythonRequirements:
    slim: true

Happy to write tests and etc with any feedback given.

@ndanielsen The patch does not work for me. I cleaned all my plugins and install from your repo. I get the following error.
