[Tom-Kingstone]

Issues addressed by this PR

Closes #592

• File settings attribute removed from XMLAdapter and placed in XMLConfig.
• XMLConfig is now an IXMLConfig and any future configs must contain a file settings attribute.
• CRUD methods have been updated to use config.File rather than _fileSettings
