Single click on Color Selector Appends # to URL

If you just Click the circle selector instead of Dragging it, it will append a # to the URL, causing the page to jump to the top.

Temporary fix until it's fixed in the repo:

```
jQuery(document).ready(function($){
$('#color-picker').iris();

// after initializing iris on your element(s)
$('.iris-square-value').click(function(e) {
e.preventDefault();
});
});
```

Reproduce the issue by initializing Iris on #color-picker and clicking .iris-square-value without dragging. Inspect the click handling around that selector; done means a single click no longer appends # to the URL or jumps the page to the top.
