Table not found error due to improper {$table} syntax

Line 37 of emfield.audit.inc
$sql = "SELECT $provider_column FROM {$table} GROUP BY $provider_column";
should read
$sql = "SELECT $provider_column FROM {" . $table . "} GROUP BY $provider_column";

This bug is found in the recommended version as well. I believe it will only produce an error when a table prefix is used.
