Fix setting medal times for gold and silver.

• Fix for new game version
• Disable lock times and validation status when you close the window

• Disable medal times input if the map is not validated

• Hide window outside editor all together
• Improve reset logic for locking times
• Window is now collapsible
• Default dimensions improved

• Added 'lock times and validation status' checkbox (useful when making small changes late in production)
• Added 'validate' button
• Added some auto-update logic around setting invalid medal times (like bronze faster than silver). Slower medals get updated if faster medals' time is increased past the slower medals time.
• Hide the window when in mediatracker or validation mode.
