Make file paths in error messages links to open the file in editor

[Aerilius]

When an error occurs, the backtrace in the output contains file paths. If these source files are found/exist, a user could click a link that opens in the editor at the correct line number.

• Whether files in backtraces exist must be checked on the Ruby side.
• The output module does not know about the editor. How should it make links that call the open on the editor without introducing a dependency?
• Check whether this can be realized as a feature instead of core functionality. Do we need to emit new events?
