Hero name bugfix and checksum adjustment

Hero names should fill in correctly in the opening Lucia's Place.

If you choose a hero or sage as an opening character, the checksum will no longer change. The feature was intended as an anti-cheating device, but I figure that people are going to use a non-hero/sage checksum, then put in a hero/sage. Cheating can be enforced in a better way... (forced streaming, for example!)
