Implement better logic for the timeship Wings of Time's short name and other properties.

[codergal6502]

• The name string index for the Wings of Time's short name seems to match that of whoever the most recently named character was.
  • This name should probably not be editable unless the name index doesn't match any other character's.
  • Research is probably needed to see the circumstances under which the name index for a character may not match that character's index other than the Wings of Time.
• The other fields for the Wings of Time likely should not be editable, since they seem random and so probably represent something meaningful other than their interpretation.
