title: Paginator for inline models in django admin
body: <p>I have this simple django model consisting of an sensor and values for the specific sensor.
  The number of values per Pyranometer is high (>30k). Is it somehow possible to paginate <code>PyranometerValues</code> by a specific day or generell apply a paginator to the admin inline view?</p>
  
  <pre><code>class Pyranometer(models.Model):
       name = models.CharField(max_length=75)                                                                             
  
  class PyranometerValues(models.Model):                                                                                 
      timestamp = models.DateTimeField()
      value = models.DecimalField(max_digits=10,decimal_places=6)                                                        
      sensor = models.ForeignKey('Pyranometer')      
  </code></pre>
