also:
- fixed config error in example `.vcxproj` files
- fixed spurious newline after JSON formatting a table
- fixed VS intellisense not detecting TOML_COMPILER_EXCEPTIONS correctly
- moved `parse_result` to a separate header
- made more internal macros require semicolons
- removed some old deprecations
- minor documentation fixes
There's no new functionality here. It's purely tooling + CI stuff:
- moved `python` => `tools`
- moved documentation images to subfolder
- moved `vs/tests` to tests/vs projects
- moved `vs` solution etc to root
- added semicolons to macros
- added cpp.hint to help VS intellisense
- migrated documentation generation to external lib
