Add niceties to achievement_group

[Samdal]

This PR adds two functionalities that I myself found useful to have in achievement_group.

1. sync_ms I added sync_ms, just like other devices (including the achievement device) 2. disable_random Just like the random_event_player device, this enables auto_select and select_random_achievement_events to operate sequentially instead of randomly.

This would require an update of the documentation, as the new features introduce new options in the device.
