Strip Signatures and Images From Email Contributions Merged

In our organization, employees are directed to include links and imagery to our social media sources in their email signatures. When users with these types of signatures email in their contributions to aha,  numerous attachments and descriptions are added to the user's comment, polluting their contribution.

It would be nice if these types of email attachments were collapsed and hidden from view.  If the reviewer of the comment was interested in seeing the attachments, she could expand some type of 'signature attachments' section of the comment.
