Debugger app

[zodern]

Right now it can be difficult to debug apps. This will be an app that helps.

Core changes

• Option in server api to start app with --debug-brk or --debug (or allow passing any arguments)
• Server api allow starting app from path instead of only registered apps. The app manager should not install dependencies.

Requirements

• Choose app or path of app to debug
• Start app and restart on file changes
• Once app starts, load node-inspector
