Send comments as robotComments (#238)

Robot comments show up in the Findings tab, instead of in the comments.
This makes it much easier to differentiate from them a reviewer's
comments.

The API requires a "runId" for the comment. I've chosen to just send a
random UUID for now, but eventually we could wire in something like a
build number or something.
