Create better way to mark specific PlayerPrefs as persistent

[yellowberryHN]

Currently, when you run a New Game or New Game+, there is specific code to wipe your stored data, while storing some data to be used again. Each persistent key is defined as a call to a StoreInfo method, which just seems really messy.

public static void ClearGameData(bool keepMonsters)
{
	int_dic.Clear();
	float_dic.Clear();
	string_dic.Clear();
	StoreInfo("version", version);
	StoreInfoInt("tried_tutorial");
	StoreInfo("volume_master", 0.75f);
	StoreInfo("volume_menu", 1f);
	StoreInfo("volume_ring", 1f);
	StoreInfo("volume_game", 1f);
	StoreInfo("volume_music", 0.5f);
	StoreInfo("volume_vibrate", 0.75f);
	// ...
}

I think instead it would be better to have list of persisted values and just run the required methods in a loop or something.
