Firefox31's toolbar is too busy

With NoScript, HTTPS-Everywhere, Torbutton, the bookmarks widget (which is two icons), the download manager, the home button, and the "vent"/menu all on the toolbar, things are getting ridiculously crowded.

I played around with the customization pref, and I think that if we move everything but NoScript and Torbutton into the vent, it's less cluttered and encourages people to click on the vent rather than simply being terrified of everything.

I am going to commit this pref into our git repo. There's probably a better way to do this customization, but this seems expedient and easier, especially given that I want to ensure that NoScript and Torbutton always have the same positioning.
