title: ipython: disable copyright and help upon startup
body: <p>when I start <code>ipython</code> from my terminal, I get following output:</p>
  
  <pre><code>Python 2.7.3 (default, Mar 13 2014, 11:03:55) 
  Type "copyright", "credits" or "license" for more information.
  
  IPython 1.2.1 -- An enhanced Interactive Python.
  ?         -&gt; Introduction and overview of IPython's features.
  %quickref -&gt; Quick reference.
  help      -&gt; Python's own help system.
  object?   -&gt; Details about 'object', use 'object??' for extra details.
  
  In [1]: 
  </code></pre>
  
  <p>Is it possible to supress the copyright and help information? After having seen it a thousand times, I start to find it a little bit superfluous.</p>
  
  <p>Ideally, I would like to see only the prompt <code>In [1]:</code> when I start <code>ipython</code>.</p>
  
  <p>I am using <code>ipython 1.2.1</code></p>
