Replace more than one forward slash
<p>I'd like to replace more than one forward slash with one forward slash.</p>

<p>Examples:</p>

<p><code>this/is//an//example</code> -> <code>this/is/an/example</code></p>

<p><code>///another//example////</code> -> <code>/another/example/</code></p>

<p><code>example.com///another//example////</code> -> <code>example.com/another/example/</code></p>

<p>Thanks!</p>

<p>EDIT: This will be used to fix URLs that have more than one forward slash.</p>
