Title: Deprecating IS_MAC in favor if strictly IS_UNIX

This patch originally addressed an issue with the IS_MAC os check in import.php, but expanded into deprecating IS_MAC in favor of using strictly IS_UNIX since the only place IS_MAC was used was in the JClientFtp Library to check for line endings. Unix and Mac use the same LF line ending.
