Compile-time snapshot of your project source

This is necessary to attach source code snippets to exceptions reported to Bugsnag. We do this by reading the project source at compile-time and stashing the result in Settings.

• *WARNING**: This feature (probably) means you will be holding all indexed source code in memory during the life of your process. And in larger projects, it will embed substantial amounts of source code in a single file, which can significantly degrade compilation time.
