NEW NPC, BUG FIXES, LINUX BUILD

THIS UPDATE IS PART OF THE STEAM NEXT FEST DEVELOPMENT RUSH.

Patch notes:

• + Added a new character, Koya, to the Hotel Lobby

• + Added more help text to battles

• + Added Special Thanks to the credits

• + Updated Linux build to this version

• = Changed the start and end screens

• - Fixed a bug in the menu

• - Fixed a bug in the tablet

I've also made some progress on the French translation, but that's taking a lot more time than I'd expected.
