Webhook: add event information

[GrinchUA]

bluecherry-apps/www/lib/mailer.php

Line 102 in d55f8e3

$event = data::getObject('Media', 'id', $argv[2]);

The function contains information about the event, why not send it to the webhook, this information will be useful for processing.

I agree it would be useful. If you want something sooner we accept PRs, otherwise I'll keep it in mind for after the 3.1 stable release.

Hi, testing has shown that mailer.php already sends detailed information about the event to the webhook, this is the example of the raw content of mentioned information:

{
  "event_name": "motion_event",
  "event_datetime": "2021-04-17T02:08:59+04:00",
  "device_id": "2",
  "device_name": "TestCam",
  "dvr_name": "Bluecherry DVR v3"
}
