Remove Suggestion Observer
Move after_save for Comments to the Comment itself

This was just evil
Remove beginrescueend
Removed unnecessary check

Why would anyone change a comment without changing anything?
Moved delivering to the mail class
Moved after_create to the controller
Moved after_update to the controller

This is a little ugly. But you can't use `changes` here.
I tried it for some time... it doesn't work...

This has to suffice for now.
