bsocial-comments moderation enhancements

- Featured comments moderation tweaks
	- Hid featured comment posts from the admin panel
	- Added Featured sudo status filter to comments panel
	- Moved Feature/Unfeature action so that it's right after Approve/Unapprove
	- Added some color
- Feedback tweaks
	- Added faved/flaged sudo status filters
	- Added some functions to hook into the delete, spam, trash stuff so counts get updated correctly
	- Removed a few functions that at this time I believe were not actually doing anything
- Fixes and tweaks to flag/fave count stuff that I found issues with while testing the changes
