New Scenes:
 * card-making scenes for Jacob, Barbara, and Raven
 * holiday concert (_many_ variations, especially involving Damien, being President, and being in Chorale)
 * playable through Dec 19

Bugs/Crashes:
 * Crash when the sparkle takes damage fixed.
 * Crash on Dec 14th if we were broke but agreed to go shopping for
   Donald fixed.
 * 'Ask Minnie about Secret Santa' option on Dec 14 now only shows up if
   you're copresidents.
 * various tabs, slides, etc
 
Dungeons:
 * Gloom units (the gradients by Dark cells) are no longer physical, so Blast
   shrapnel will no longer hit them.
 * Spells that target yourself now use the normal spell-casting framework,
   so they will deduct MP and not fire off immediately. (Fixes Boost Strength
   and Longjmp being free casts)
 * Spirit Echoes units no longer movable, so teleport circles won't push them
   around. (Fixes an unnamed unit wandering about with you when you teleport.)
 * Now lock the dungeon UI when the say-slidein and say-slideout screens are
   up, so you can't wander around the dungeon while giving up so much.
 * Now gives a different examine description when you're aware a wall is illusory.
 * Living units (like the player) are no longer objects by default, so you
   can't fracture yourself.
 * Now clear out player statii when showing the dungeon lobby, so that if
   you were blind when you exited the last dungeon you no longer wind up STILL
   blind entering the next tutorial.
