Fix for bypassing moderation when making comment public (Bug #1171310)

To get a private -> public comment moderated the system needs to check:
* if the view has approvecomments set to 1
* if the submitter has checked the make public checkbox
* if the submitter is not the owner of the view
* if the view is a group view
* if the approvecomments are set per view

And update the comment table accordingly and now sends off notify
message if needed.

Removed some unneeded variable declarations
