Add a Continent Size setting (Continents size in relation to each other)

As of right now the game always generates continents of the same size and "forces" a symetrical playfield. For example if you setup a game with 2 continents and 6 players it will always generate 2 continents of similar size with 3 players on each.

Consider adding a Continent Size map setting below Continent Spread and Continent Form with similar drop down options:

Regular: Generates continents of similar size

example: 2 continents 6 players - 2 large continets with 3 players on each

Chaotic: Generates continents of different sizes

example: 2 continents 6 players - 1 huge continent with 4 players and 1 smaller continet with 2 players

Random: Choses an option randomly
