Bug 7154: Modification in borrower attributes
* group some attributes for a more friendly display
* allow a link between a borrower category and an attribute to display
it only for the specified category
* Attr classes filled with AV 'PA_CLASS' category (you have to create AV
with a new category 'PA_CLASS' to fill class list)
this patch add 2 fields in borrower_attribute_types :
category_code
class
