[turba] change turba display layout

[Markus Dejmek]

Hi, 

I have a quick question. I want to change the turba display layout. 
My college did this last year. 
He changed the files:

turba/templates/add/add.inc.hca
turba/templates/advanced/criteria.inc.hca
turba/templates/display/display.inc.hca
turba/templates/edit/edit.inc.hca

In the new versions of horde this files don't exist anymore. 
I did have a look at the new files, and I can't figure out how
to change the view. 

I hope someone of you guys can help me. 
A hint, or a small example how to get a another display layout would 
be helpfull. 

thanks a lot

Markus
