[development] new sorting.module

[Robert Garrigós Castro]

Hi all,

I needed a new type of node sorting for a drupal implementation I'm 
working on and I wrote a simple sorting.module that does the job. I 
thought it might be a nice feature to have for the new 4.7 so I uploaded 
a zip file with the module and a couple of patches here: 
http://drupal.org/node/37899

I will appreciate any feedback on this in order to evaluate the 
possibility to have something ready  for a 4.7RC.
