Sihai's Legacy - MC Update

This update doesn't add any new days, but is instead implementing the new MC update.

• MC has gotten 2 more body types. All sprites have been adjusted.
• Almost every CG that includes the MC has gotten 2 more versions.
• Slight adjustment to the start of the game

From this point onwards, the free version will be following the same cycle as the patreon one, releasing one day per character every two weeks!
