Toolbar buttons use mootools. Change to jQuery
Replace mootools code with jQuery

instead of this:
```
<button type="button" class="btn hasTooltip" title="<?php echo JHtml::tooltipText('JSEARCH_FILTER_CLEAR'); ?>" onclick="document.id('filter_search').value='';this.form.submit();">
```
We can use this:
```
<button type="button" class="btn hasTooltip" title="<?php echo JHtml::tooltipText('JSEARCH_FILTER_CLEAR'); ?>" onclick="('#filter_search').val='';this.form.submit();">
```
