Memory: Fetching current main character

[orkaboy]

Some routing at the beginning of the game requires knowing which character is the current main character. Since this is random from the start game screen, we need to read it from memory.

We need a function that can query memory "Who is the current MC?" and return "Valere/Zale". Enum, boolean doesn't matter too much which.
