Expandable Categories 1.2

Turns the Categories panel into a collapsible list. Inspired by x00's Category Accordion plugin.

It works best with root categories as headings enabled.

It is released under the GPLv3 and may be released under a different license with permission.

Placing $Configuration['Plugins']['ExpandableCategories']['ExpandActiveOnLoad'] = FALSE; in your /conf/config.php file will keep the full list collapsed on page load.

Tested working on 2.0.18.x and 2.1
