Updated gitignore

Since I moved org-clock saves to a dotfile.
Updated gmail-edit-mode to raise Emacs

Moved the ns-raise-emacs function into the init file for edit-server.
May end up changing this later. Haven't used edit-server a ton.
Change end- and beginning-of-buffer in dired

end-of-buffer and beginning-of-buffer now take you to last file and
first file in the directory, respectively.
