Fix frontend input renderer.

[mimarcel]

IN SHORT:
Customer attribute "ho_import_profile" has frontend input set to "text". Because the value for the ho_import_profile attribute of a customer is an array, frontend input class Varien_Data_Form_Element_Text is unable to correctly display the value.

DETAILS:

• Currently, when in developer mode, the following error is received when trying to edit customer in admin:

• The ho_import_profile correctly works for products where frontend_input_renderer was directly specified to class class Ho_Import_Block_Adminhtml_Catalog_Product_Helper_Form_Profile.

SOLUTION

• The ho_import_profile for customer should have the frontend input renderer set to class Ho_Import_Block_Adminhtml_Catalog_Product_Helper_Form_Profile.
• However, customer eav attributes don't have a frontend_input_render field, so we will change frontend_input to "ho_import_profile". When Magento tries to find the renderer it will automatically find it from the frontend input to be Varien_Data_Form_Element_Ho_Import_Profile.
