Added Settings class & Settings file

- All settings are moved in a new Settings class
- Settings can be loaded by parsing an INI file
- A default INI file is generated with default settings
- By default, loads MinecraftClient.ini if no command-line arguments are
used
- Another INI file can be loaded with MinecraftClient.exe MyFile.ini
- All the config files can be renamed or moved, just edit the INI file
- A title for the console window can be specified in the INI file
- Regular command-line arguments still works but will probably be
simplified in the future.
- Smal code optimizations and adjustments
