Mutes now hold outside of chat, and /ban and /mute report the punishment they actually applied.

• Muted players can no longer bypass their mute with /me or the private message commands. The blocked commands are configurable under mute-command-blacklist in config.yml and are matched on the command name alone, so /minecraft:msg is caught as well. Contributed for Velocity by NTMFanSolidius in pull request #1 and ported to Spigot and BungeeCord from there.
• /mute <player> <id> applied the ID's escalation level but always announced a mute: an ID whose level is a ban stored a ban, left the player online and talking, and /check then reported a ban nobody had handed out. Both commands now resolve the level first, report the type that was applied and kick when it is a ban.
• /mute now honours only-admins IDs, which so far only /ban checked.
• New punishments.require-id option: with it on, /ban and /mute only accept IDs from ids.yml. Staff with bansys.ban.admin keep free durations unless punishments.admin-bypass is turned off.
