Config option to limit the trace output on exceptions to 'App\'

[lsrur]

When an exception occurs the back trace is unnecessarily long. A config option to limit the backtrace to the App namespace would be very comfortable.

This would be best placed in the Ray desktop App:

• Option to auto-hide non-app files in the stack trace.
• Each trace has an icon to show captured vendor files.
