Added new query filters to dynamic segments

Our dynamic segments have become even more robust with the addition of new query filters. You can now create segments based on:

• Domain Match: Segment subscribers based on their email domain or set of domains.
• Variable Match: Segment subscribers matching specific provided custom subscriber data values.
• Interaction with Tagged Content: Segment subscribers who have opened or clicked on messages and/or auto-responders associated with specific tags.

As a reminder, we've also integrated suppression segment support. You can now use outside suppression files in MD5, SHA256 and SHA512 format as excluded segments.
