The pre-Obsidian release

This release should address most raised issues. If you encounter any problems, please open an issue on GitHub.

I'll leave this release open for about a week as I prepare documentation and clean up unused code in preparation to propose this plugin to the Obsidian Community Plugin repository. Stay tuned.

Changes

• Added configuration option to set vault subdirectory as Quartz content root.
• Added configuration option to set frontmatter key to mark notes a publishable (was "publish", matching Obsidian Publish)
• Added support for all embed types that Quartz supports (was images only)
• Added support for fine-grained access tokens.
• Added new logo
• Disabled Excalidraw embeds (currently broken, will be fixed in future release)
• Added documentation as Quartz website. It can be found at: https://saberzero1.github.io/quartz-syncer-docs/
