Clean-stack Packages

Meant to be used with [clean-stacktrace][] as mapper function. Makes absolute paths inside stack traces to relative paths.

Plugin for `clean-stacktrace` lib. Parse each line to get additional info like `filename`, `column` and `line` of the error.

Modify given `err` object to be more useful - adds `at`, `line`, `column`, `place` and `filename` properties and also cleans stack traces.
