Subject: [PATCH] Validation change for Text type attributes. The call on
 Mage_Eav_Model_Attribute_Data_Text:67 to empty returns true of a value of "0"
 is entered, as specified in the PHP spec. This prevents the entry of zero on
 the backend admin for fields. Zero should be a valid value, as it was in our
 case.

No unit tests were created, as no unit tests exist currently for the Eav module.
