Bring back "Sort Faces" command.

This was the old Ctrl + FKEY in object mode, now it's in
edit mode and is part of the Ctrl + FKEY menu (Faces).

I also assing this to the Ctrl + Alt + FKEY, but Matt please
check this and feel free to change (or tell me and I will change).

Still there is no "reverse" function, but I commit now to finish
in my home.
