* implemented crash reporting for all goroutine panics that aren't handled explicitly * implemented crash reporting for all goroutine panics that aren't handled explicitly * changed node defaults back to originals after testing * implemented panic handling for all goroutines that don't explicitly handle them, outputting the stack trace to a file in crashreports * handling panics on all goroutines gracefully * updated missing call * error assignment * implemented suggestions * path.Join added * implemented Evgeny's suggestions * changed path.Join to filepath.Join for cross-platform * added err check * updated RecoverStackTrace to LogPanic * updated closures * removed call of common.Go to some goroutines * updated scope capture * removed testing files * reverted back to original method, I feel like its less intrusive * update filename for clarity
