not all params to be used are in function prepareParameters in EtsyApi.php

[gijsve]

I needed to change line 115 in function prepareParameters in EtsyApi.php to:
$allowed = array("limit", "offset", "page", "sort_on", "sort_order", "include_private", "language","was_shipped","was_paid","shop_id");

To make it work the way I wanted. Else was_shipped etc. are ignored.
