Ectoplasm mini fixes for incorporeal legs

[Stadler76]

• If the player has the perk, but the legs aren't incorporeal this is now being silently fixed.
• The conditional below has been reverted to avoid the player getting the perk twice.
• Tidied the TF blurb (multi-lines instead of one extremely long line and make use of the parser tags)
• Changed player.hair.type === 2 and so on to player.hair.type === Hair.GHOST and so on (Readability++)
