Add a changed timestamp field to Variation groups and items

Looks better to do this in two updated:

 --------------- ----------- --------------- -------------------------------------------------------------------------------------- 
  Module          Update ID   Type            Description                                                                           
 --------------- ----------- --------------- -------------------------------------------------------------------------------------- 
  commerce_vado   8203        hook_update_n   8203 - Add the 'changed' field to 'commerce_vado_group' entities.                     
  commerce_vado   8204        hook_update_n   8204 - Add the 'created' and 'changed' field to 'commerce_vado_group_item' entities.  
 --------------- ----------- --------------- --------------------------------------------------------------------------------------
