Assorted ingame text changes

[fenhl]

This PR makes 3 changes to the in-game text:

• Dampé's diary now says “visit” instead of “enter” for overworld hint areas. It still says “enter” for dungeons, the Temple of Time, and the Thieves' Hideout. I think this sounds more natural, and avoids being potentially misleading in the cases of Hyrule Castle (where “enter Hyrule Castle” could be interpreted to mean the garden locations only) and Gerudo Fortress (where “enter Gerudo's Fortress” could be interpreted to mean the Thieves' Hideout). I've also cleaned up the grammar for oGC and iGC:

  -enter #outside Ganon's Castle#
  +visit #the outside of Ganon's Castle#
  
  -enter #inside Ganon's Castle#
  +#enter Ganon's Castle#

• The Temple of Time altar now uses singular forms for single-item win conditions, e.g.:

  -automatically granted once 1 #Spiritual Stones and Medallions# are retrieved
  +automatically granted once 1 #Spiritual Stone or Medallion# is retrieved

• Dungeon items sold in shops no longer drop their apostrophes, e.g.:

   Silver Rupee  10 Rupees
  -(Dodongos Cavern Staircase)
  +(Dodongo's Cavern Staircase)
   Special deal! ONE LEFT!
   Get it while it lasts!
