Prevent klipse to emit empty html content

[sanel]

When :klipse is set to {} (or not present at all) in config.edn, it will emit this code:

<link rel="stylesheet" type="text/css" href=nil>
<script>
window.klipse_settings = null;
</script>
<script src=nil></script> 

where browser will fail with GET request for given resource, which is nil. Here is a small patch to mitigate this (I've added it against blue_centered theme, but should be applicable to other themes as well):

--- a/resources/templates/themes/blue_centered/html/base.html
+++ b/resources/templates/themes/blue_centered/html/base.html

 {% if post.klipse %} {{post.klipse|safe}} {% endif %}

 </body>
 </html>

Thanks for the patch. I'll look at applying it to the rest of the themes when I get a chance.

I think it may be better to solve this further upstream, so you don't need to do this in every theme.
