Artifact Evaluation Artifact - Additions to Research Paper Review Form

We extended the research paper review form so that PC members could communicate information to the AEC.

Besides asking for information about what kind of artifact the PC members considers to be appropriate to support the claims of the paper, we also asked for general comments. The goal of that field was to gather questions the PC members had about the paper, which might have been answerable if they had had access to the artifact (and thus, the AEC might want to look at when evaluating the artifact with respect to its consistency with the paper).
