Update to fix problems in the demo version — Severed Love Steam update #1164878

Thank you to all the victims of the “Limb-Severing Devil Case” who are enjoying the full voice demo version! I have updated the demo version to address some minor issues. Changed to not play voices and SEs while skipping to fix a bug that prevented Mac users from skipping voiced dialogues. The language setting icons on the game startup and configuration screens have been changed to a country-neutral design. Fixed other minor bugs and typos.
