Partial fix for null PlayerManager.PlayerData dictionary

For some reason, even though I tried making the PlayerManager a static
class which would get initialized with the MajormudMainGame object, the
damn thing would be null every time the CreateNewPlayer method was
called. So I'd love to understand why that's happening, but I'm now able
to have more than one person log in and make a character when I couldn't
get past the Race selection view prior to this
