Made a couple of small display/CSS changes, might be useful for others

This is for version 2.1 of JCL.

I noticed that on my site, when I had the expand/contract symbol on the left of the category, there was no space between it and the category name.
To fix this I did the following in jquery-categories-list.php

On line 325 change:
$cssRule = $instance['layout'] === 'right' ? 'right' : 'left';
to
$cssRule = $instance['layout'] === 'right' ? 'left' : 'right';
(swapped ‘right’ and ‘left’ after the ternary operator)

On line 327 change:
$childLink .= '<span class="jcl_symbol" style="padding-' . $cssRule . 'left:5px">';
to
$childLink .= '<span class="jcl_symbol" style="padding-' . $cssRule . ':5px">';
(removed the hardcoded ‘left’)

I also wanted to add a CSS style to make it so that Categories with no children could be styled with a bullet point, and thus still be indented.
To do this, I added a conditional check and added a new CSS style to elements which do have children so they could be differentiated.

On line 332 change:
$html .= '<li class="jcl_category" ' . $styleAttribute . ' >';
to
$html .= '<li class="jcl_category'. (!empty($child_html) ? ' jcl_category_has_children' : '').'" ' . $styleAttribute . ' >';
(added a ternary to check if the category has children and add a style to the listitem if it does)

Then in your theme’s CSS file (e.g. styles.css) you can style Categories with children differently from those without children, e.g. in mine I have:

.template-front-page .widget-area .widget li {
    list-style-type: disc;
    margin: inherit;
}

.widget .jcl_widget li.jcl_category_has_children {
    list-style: none outside none;
}

Which gives me bullet points on all lists in widgets, but not on the categories which can be expanded.

Hope it’s of use to somebody anyway.
