Build 25808460

New: first-time tutorial
New players get a short walkthrough the first time they reach the main menu: open Clip Studio, add the line missing from a copy of the Cosmonaut Astronaut scene (type the original or write your own), test it in the Dub Stage, then listen to the line and record it.
SKIP TUTORIAL is on screen the whole time. Play it again any time from Settings → General → Tutorial.
Fixes
Fixed some converted packs where the original voices didn't play when listening to a line, or the music played twice.
Fixed some converted packs that came out with a separate character for every line. Convert these packs again to fix them.
Fixed a couple of Clip Studio issues that could overwrite a line's audio.
