Added option to turn url encoding on and off

[bboughton]

Rails url helpers escape special characters when creating urls, so when jQCloud escapes the url it double escapes it.

<script type="text/javascript" >
  var word_array = [{text: "John's Bday", weight: 1, link: "/posts?tag=John%27s+Bday"}]
</script>

Becomes...

<span id="example_word_1" class="w1">
  <a href="/posts?tag=John%2527s+Bday">John's Bday</a>
</span>

Which doesn't link correctly.
