Use ClamAV to scan uploaded files
rhbz901401 Add preliminary support for InDesign IDML documents

Limitation: mysqld's default max_allowed_packet is 1MB, which means
BLOBs must be less than 1MB.  (IDML files tend to be large.) We either
need to split files into multiple BLOBS, or to avoid bloating the
database, perhaps we should store in the file system.
