Configuration - If PROVINCE_LIMIT is Empty then State-Province Select Should be Empty

Currently if config->PROVINCE_LIMIT is empty, we load ALL state_province rows into the select options. This causes problems loading the Contact add/edit forms (and any profiles w/ state fields). For now, change the behavior to just load an empty <select> for this case.

NOTE: We recognize that this is not optimal - and will implement a widget for this in a subsequent release which pulls state-province options based on the selected country.
