Index Offset for the Array modifier

Already asked this once, it would be a new feature for the array modifier, useful mainly for modelling.

The idea is to add an "index offset" option next to the count, this would allow to displace the mesh to the ‘left’ or to the ‘right’ in the list of transformations, so if you set the copies to 5 and offset to -2 the array would look centered. But you could offset to any value... lets say you set copies to 2 and offset to 10, it would be like you had 12 copies but only see the 2 from the end.

I've seen the concept in other softwares and it's a nice feature, there's a place for it in the gui and should be backwards compatible... internally it would add an extra transformation matrix to the base mesh -in the case it is used-
