[Moodle] 修正Moodle 1.9.9無法在某些瀏覽器正常使用HTML Editor

修正方法需些改兩個檔案~ 分別如下：

/lib/moodlelib.php

line 6519 } else {
line 6520 return 1;
line 6521 }

/lib/editor/htmlarea/htmlarea.php 

line 2408 //alert("Mozilla < 1.3 Beta is not supported!\n" +
line 2409 // "I'll try though, but it might not work.");
line 2410 return 'HTMLArea.is_gecko';
line 2414 //return false;
line 2415 return 'HTMLArea.is_gecko';

It Works!
