Add support for fetching comments posted since a specific date

[koke]

Adding a "since" option to wp.getComments and get_comments() could help reducing bandwidth used by mobile apps.

Probably useful for themes/plugins too

Added patch for it. Please code review, not sure if some kind of date validation needs to be added, or $wpdb->prepare() handles that already.

Just like WP_Query requires a clauses or posts_where filter to get posts in a date range, comments would require a comments_clauses['where'] filter.

See Codex for posts_clauses: ​http://codex.wordpress.org/Plugin_API/Filter_Reference/posts_clauses

I'm not sure why it's closed. A filter can be used but option would be nice to have.

I think this is handled by WP_Date_Query. #18694

Is it? I don't think that will mean you can use it through XML-RPC but I can look at that.
