Add connector for Comments

[frankiejarrett]

Comment actions should be added as a core context of the Stream plugin.

Possible actions:

• Created
• Updated
• Replied
• Approved
• Unapproved
• Spammed
• Unspammed
• Trashed
• Untrashed
• Deleted
• Comment Flooding
• Duplicate comment attempt

Added Comment flooding since WP checks for the last commit you have before allowing you to post a new comment.

@fjarrett Regarding 'Comment::Replied' action, would it be stored as a single record if a user replied to a comment, or would a 'Comment::Created' record be created as well ? I took the approach of not adding the 'Created' record in this scenario, hopefully it'd be mitigated by users ( or extensions 👍 ) querying the database.

@fjarrett Actually the same thing happens with 'Comment::Approved' since some comments would get approved automatically on insertion, while others would not. I think this scenario requires an explicit second record for the approval action, to make it easy for users to query such actions, otherwise the query for approvals would need to check meta table for comment_approved meta field. Thoughts ?

@fjarrett Final result:

• Adding a comment, while auto-approve is on, triggers two records ( created / approved )
• Adding a reply, adds an extra records ( 2 or 3 records per reply, depending on auto-approve )

Let me know what do you think should happen here.
