Add "Send to Science Officer" button to Editor Panel
An editor should be able to send a submission to the science officer at any point in the article's lifecycle.
Every article needs to go to the science officer initially, for signoff on the article and proposed reviewers. The first time, the science officer must either approve or not approve the submission to proceed, leaving any notes in the general discussion thread. After this, the editor should still have access to the send to science officer button, but when the science officer is ready to return the submission to the editor, he or she should simply leave a comment in the general discussion thread and hit a similar button to "return to Editor" without rendering any approve/do not approve decision again.
