LifterLMS Helper Version 3.3.0

June 14, 2021

This plugin is now included by default via the LifterLMS core in versions 5.0+. Installing this plugin directly will use the plugin version instead of the version included with the core. Direct installation is likely only required for development purposes when using LifterLMS 5.0+.
The main function llms_helper() is declared conditionally when the class LifterLMS_Helper is not yet declared.
Added a constant LLMS_HELPER_DISABLE which allows disabling of the plugin.
Distribution release zips now include a composer.json file to allow for installation via composer.
