Virus scanning of uploaded attachments

Attachment Checker allows all attachments to be scanned with an external 3rd party anti-virus scanner after they are uploaded.

This addresses the following issues:

When an attachment is uploaded, it is added into a queue for scanning, so that users do not have to wait for the scanning to complete, which may take some time especially for large files. 

If attachment is found to be infected, a comment will be added in the issue to inform users for follow up.

Any non-zero exit code by the virus scanner is treated as infected.

Virus scanning can be configured at Attachment Checker ConfigurationVirus Scanning
