Kenshin's Hide And Seek

Fixes:

• Debug menu options now work when a spectator
• Newly added seekers after being found in block hunt are no longer invisible
• Spectators can no longer take damage and/or die
• Spectators can no longer interact with the world/players
• When making a player no longer invisible, their skin toggles will be restored instead of all being off
• Menus will now check for permissions on click, not just on open
