Subject: [PATCH] Rename .emacs if it exists in the installer(#1037)

If user has a $HOME/.emacs file, the prelude installer script
will install just fine, but when starting emacs, nothing will
take effect because emacs doesn't load .emacs.d/init.el if .emacs
exists. Because this is confusing for new users, the installer should
default to renaming this file to make emacs actually load prelude.
