UT text box gen v2.4.0

• Added a universe selector and grouped the characters in it, to reduce the lenght of the list. If you can't find an AU, it might have been grouped inside of the AU it's based on (for example: Underfell, Primus!Underfell and Fallen Kingdom are inside of the Underfell group).


• Added a bunch of new default messages.


• Added all of Asriel's expressions.


• Added the default sprite of Primus!Underfell Papyrus.
