Multi checkbox support

Hi,

I needed to support a list of category in one of my widget by using page builder. ( an input checkbox with a name ‘xxx-categories[]’).

That code is not recurent but it work fine for me.
I have modified the js file “js/panels.admin.panels.js” as below :
Page builder (https://www.ads-software.com/plugins/siteorigin-panels/) version : 1.3.9
