Title: Move the game options out of config.vl.

When the GameOptions class change, the game cashes due to InvalidClassException.

As said, [serialization shouldn't be used for persistence](http://stackoverflow.com/questions/8335813/java-serialization-java-io-invalidclassexception-local-class-incompatible), especially for options.

This patch makes the GameOptions class has its own storage at `game_options.properties`, using the Properties class.
