Simplify response error handling

[gmarz]

A follow up from #1793

This issue is two parts:

1. Design a way to encapsulate and simply error handling

2. Add DebugInformation to response that pretty prints error information for debugging and issue reporting

[Mpdreamz]

2. is implemented and is immensely useful
3. We are going to stick to our "progression over perfection" mantra for now. The error/exception handling is already greatly simplified from 1.x.
