Changeset 8190

Message:

Blogs: Support post comment synchronization in the activity stream.

Previously, if a reply to a blog post was made in the activity stream,
the reply would only exist in the activity stream and not as a comment
for the blog post.

This commit:

• Adds a blog comment whenever an activity reply is made under a blog post activity entry
• Adds an activity comment to the blog post's activity entry whenever a blog comment is made
• Checks to see if the blog post is open for comments (whether manually closed or due to age) (see r8189) to determine whether the activity item can be replied to
• Handles content edit synchronization to either the post comment or the activity comment
• Handles deletion synchronization to a degree

See #5130
