title: Line style and x_jitter for seaborn factor plots
body: <p>Seaborn factor plots are fantastic but how do I influence line style (e.g. dashed etc for better b/w readability). And how do I apply "x_jitter" so the different confidence intervals don't occlude each other?
  Thanks!</p>
  
  <p>Here is an example that does not have those changes applied.</p>
  
  <pre><code>&gt;&gt;&gt; import seaborn as sns
  &gt;&gt;&gt; sns.set(style="ticks")
  &gt;&gt;&gt; exercise = sns.load_dataset("exercise")
  &gt;&gt;&gt; g = sns.factorplot(x="time", y="pulse", hue="kind", data=exercise)
  </code></pre>
