Fixes of the past 2 weeks — False Skies Steam update #1425426

Not nearly as many as last time: -Added another NPC to Cephi Palace. -Removed the flashing when selecting text. -Changed where the on-loss return point is after clearing the Palace of Io. -Added an NPC to Io where there should've been one. -Fixed the special ability of Defenders and Guardians not cancelling when their attacks are backed out of. -Modified two text boxes. -The world map menu should now highlight the selected menu item. -You'll now get the Luminous Cavern marked on your map when the time comes to go there. -Did some behind-the-scenes fixing up of stuff that hopefully shouldn't affect anything. -Fixed an issue with an Abyssal Tower map where you could get fall down a pit and get stuck.
