Cell doesn't get loaded on IE8

Hi, I was checking how our website looks on IE8 and it seems that it doesn't show the sage cell. You can look at it yourself at http://devel.findstat.org/DyckPaths/ (will be replaced by www.findstat.org/DyckPaths/ the next hours/days).

In the header, we have
```
<script src="http://sagecell.sagemath.org/static/jquery.min.js"></script>
<script src="http://sagecell.sagemath.org/static/embedded_sagecell.js"></script>
<script>sagecell.makeSagecell({"inputLocation": "#sagecell"});</script>
```
and in the body
```
<div id="sagecell-a4e69a95-c918-46af-852e-97744ab591b5"><script type="text/x-sage">D = DyckWords(3)
for d in D:
    print d
    print d.area()
    
d = DyckWord([1,1,0,0,1,0,1,0])
print d.to_132_avoiding_permutation()</script></div>
<script type="text/javascript">
$(function () {
    sagecell.makeSagecell({inputLocation: '#sagecell-a4e69a95-c918-46af-852e-97744ab591b5'});
});
</script>
```

IE8 says
```
'console' is undefined
embedded_sagecell.js
```
Other browsers show it properly...
