Add SettingDataVersion and Introduce SettingFixer

[jvnpr]

Description

Adds a new game setting to store settings data version, and creates the SettingFixer function to deal with conversions.

Changes

Previous Behavior

The game has no way of knowing what build a settings file was created for, or if any conversions need to be performed.

New Behavior

Setting files now store a data version.

Fix Implementation

Creates a new game setting eGameSetting_SettingDataVersion and associated uiSettingDataVersion to store the current version of the given settings file.

Creates the following functions of the class CMinecraftApp:

• SettingFixer(): Called from Windows64_Minecraft at game launch, runs checks to see if a setting file exists, and if one does, what settings data version it has. If the settings data version does not match the currentSettingDataVersion, it will perform any necessary conversions to settings data. At the moment, no conversions are implemented.
• GetSettingsFileLoaded() and SetSettingsFileLoaded(): Two new helper functions which modify the class variable static bool settingFileLoaded

Modifies Win64_LoadSettings() to call SetSettingsFileLoaded(true); when a settings file has been successfully loaded.
