API ExpandCurrencyList

Alters the expanded state of a currency list header.
 ExpandCurrencyList(id, expanded)
== Arguments ==
; id : Number - Index of the header in the currency list to expand/collapse.
; expanded : Number - 0 to set to collapsed state; 1 to set to expanded state.
== Notes ==
* This function affects the isExpanded return value of the API function, but has no immediate impact on the currency UI (which caches the expanded state when it is shown).
* Currencies under collapsed headers are still available to , so this is a purely visual switch.
