Title: Validation change for Text type EAV 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.

Unit test added. I apologize for not including that initially. I closed the other pull request.
