Club shortcut: a rail group for "where is my club on tonight"

Adds an optional rail entry per club that lists every channel whose EPG
mentions the club within the next three hours, with the matching kick-off
instead of the usual Now/Next. Only sport and free-to-air groups are
scanned (NFL excluded), so the scan stays cheap and quiet.

Which clubs appear is a per-TV setting: the signed-in viewer's own club is
on by default, and every club can be switched on or off under Einstellungen
-> Vereinsmenüs, so a household can follow more than one.

Crests are trademarks, so the icon is a plain shield in the club colours.
