CHANGE: Now requires CGSimplePWA as this module does not generate it's own service worker.
CHANGE: Separate the cgWebPush core library from the jquery plugin. So that you can have browser-only integration.
BREAKING: You now must explicitly include the modules/CGWebPush/lib/cgWebPush-jquery.js script if you want the old functionality.
Improvements to the service worker for push notifications.
BREAKING: Update all dependencies... Now requires PHP 7.1+, gmp, curl, and mbstring plugins.
Bug fixes and minor enhancements in the UI.
