Add a server monitoring file changes and re-rendering files, while providing them on a webby interface.

[kutis96]

This would be pretty cool for actually using spacedoc for something, and authoring spacedoc documents.

Goals

• Research how this is done in other projects
  • IntelliJ has a pretty nice built-in webserver similar to this; so does Jekyll and suchlike.
• Introduce spacedoc projects
  • Configure which files are to be loaded as sources, and which are to be excluded, which files/directories are to be checked for changes anyway and triggering a client-side refresh even when there's nothing for spacedoc to re-render
• Run a webserver hosting the current directory
• Automatically scan project directory for file changes, and re-render changed files
• Trigger a client-side refresh when files are rebuilt
