[OS X Emacs] Merge All Frames from Preferences.el

[Cuauhtémoc Salazar]

Thank you David,

I tried your suggestion, adding your code at the end of my Preferences.el but unfortunately Aquamacs still opens each file on different frames.
The complete Preferences.el is below.

I also have a non-empty ~/.emacs file, as I also use console-mode Emacs for quick editing. Does ~/.emacs affect Aquamacs?

Thank you,
Temok
