* lisp/progmodes/ruby-mode.el (ruby-mode): Add `ruby-mode-set-encoding'

Browse source 
to `after-save-hook' instead of `before-save-hook', because then
we know exactly what encoding was used to write the file.
(ruby-mode-set-encoding): Use `last-coding-system-used' instead of
guessing.  Call `basic-save-buffer-1' after modifying the buffer.
