New function occurrancelist_all added so that queries will return all name variaitaions

This function is an attempt to match the results of the function `occurrencelist` to the results returned by a query completed without the API at http://data.gbif.org/ .  A single name is supplied to the function along with any optional functions that should be supplied to `occurrencelist`.  Please suggest a better name for this function if you think of one.  This function still requires accompanying help files.
