All About Grouped Players

Bug Fixes

Fixed an issue where if a player is grouped with other entities but its group members are not configured in the card, only the configured players volume will adjust (instead of controlling the whole group). Override this behavior by setting the new YAML option group_volume to true (more on that below)
Restored behavior when clicking the group icon in a player chip shows the Grouped Players menu.
The bottom menu now auto-dismisses when “More Info” is selected (not a grouped player update, but it's the only thing I had that wasn't).

Added group_volume, a per-entity option that overrides the default group volume behavior. Set to true (default when grouped members are configured) to always control all group members with the main slider/stepper, or false to always control only the selected entity (even if it’s part of a group).
- You may desire to set true in scenarios where only one entity is configured but is grouped internally. This will sync the volume with non-configured players if they are grouped with the configured entity.
Closes #22

The master player in a group will now appear (if configured) in the Grouped Players menu along with its group members. This allows individual control of the master player volume without having to override the default behavior with group_volume
