title: Make emacs never open up a new frame
body: <p>How would you set emacs up to never create any new frame. If I want frames, I will do that from inside emacs. </p>
  
  <p>Annoyingly, whenever I click a file from a file manager outside emacs, this opens up a completely new instance of emacs, with all the long loading time going along with that. </p>
  
  <p>Opening a bunch of files, each taking like 5 seconds to finally load is not very convenient.
  So what I want to do is this: Whenever I click a file on the file manager, I want that file to be opend up in the one instance of emacs that is already running as a new buffer. </p>
  
  <p>How would I do that?</p>
  
  <p>Using emacs 24.3.1 on Fedora 19 with Gnome 3.8.4</p>
