The intel framework can now indicate which node discovered a
hit on an intel item through the new "node" field in the
Intel::Seen data structure. On clusters, this field will
contain the name of the node where the hit was seen.
- Intel importing format has changed (refer to docs).
- All string matching is now case insensitive.
- SMTP intel script has been updated to extract email
addresses correctly.
- Small fix sneaking into the smtp base script to actually
extract individual email addresses in the To: field
correctly.
