Alias plugin abouts with "Unable to retrieve template" error

[arabold]

After patching the Alias stack manually (due to issue #85) I cannot deploy anymore at all :) Now the alias plugin aborts with an error:

Error: Unable to retrieve template for my-project-dev-dev: undefined

I'll spend some time debugging it locally but posted this stack here for reference.

Oh, the issue is that the manually patched template now is YAML instead of JSON. That's why the parser fails with an error. Stupid me... I guess this could be some kind of a feature request but then, on the other hand, if you use sls the way it is supposed to, you should never run into this scenario in first place.
