[tryton] Selection Field Default Value

[Oscar Tark]

Hello,

I'm trying to modify a field for Parties which is a selection field. We had 
installed a module for declaring Tax included and Tax Exluded for specified 
parties so that when doing a sale it is automatic. Now the Requirment is 
that we have the Value at index price_type[0]{ "Tax Included" } 
programmatically known as 't_inc' set as the default value whenever we 
create a new Party, is there any way to do this?

Thanks!
