Add documentation explaining the optional 'target' parameter that allows restricting announcements to specific usergroups like 'vip', with all users receiving the announcement by default if not specified.
Create a new schedule configuration file that allows defining automated announcements with flexible scheduling options.
Supports two scheduling methods:
- Interval-based: every X seconds/minutes/hours/days
- Cron-based: standard 5-field cron syntax for precise scheduling
Announcements can use presets (discord, restart, event) or custom title/text combinations.
Includes comprehensive documentation and commented examples.
