Consider showing Synaptic quick introduction
We disable the “Quick Introduction” window which by default would be shown at Synaptic’s first startup (see commit 2d1fbe0a). I think that the introduction contains information that is helpful for users unexperienced with Synaptic.
On the other hand, having a dialog pop up everytime Synaptic is started in a new Tails session could be annoying.
