nofollow link

[strobotta]

Hello,

in my tagcloud I want to have rel="nofollow" attributes in the anchor to prevent search engines follow the links (because this would create an endless loop as the links link to each other).

I added an option parameter for the call so that it may look like this:

$(document).ready(function() {
  $("#tagcloud").jQCloud(word_list, { randomClasses: 3, nofollow: true });
});

The patch to the jqcloud-0.2.4.js looks as follows:

Could this maybe considered in a future release? Thank you.
