ConfOxide – Refactor Everything!

 - Completely refactors settings, minification, margin, & compiler invocation code
 - Kills ~1,400 lines before new tests
 - Includes test coverage for actual VS functionality (needs to be expanded)
 - Switch to JSON file for settings
 - Proper support for default values in settings, including new settings & property highlighting
 - Lots of bugfixes
 - All compilation & minification behavior is now fully consistent, except for a deliberate difference in Markdown.
