Fix for daily timers. Minor family fixes

[Ubaware]

• Fix for daily timers in Server.getTimeLeftForNextDay().
• Family fix to prevent player from adding themselves as a junior. Noticed by @BHB88.
• Minor family daily reset fix.
• Stopped safety charms from being used up when you die in Dojo. Noticed by @Lame.
• Added server code (didn't change NPC) to update guild leader. The first player's info sent in MaplePacketCreator.showGuildInfo() is the leader. Noticed by @BHB88.
• Prevents deletion of characters that are guild leaders or in families, or have pending world transfers. Similar to GMS.

Could you split every fix into a separate commit next time so that the code is easier to review?
