pidgin/nest

Add how to submit a bug report and debugging sections

Tackling both of these at once since they are related (a lot of the times to
submit a good bug report you need to provide a debug log or crash dump).

The contents of these sections are heavily based off the content of the old
wiki pages, primarly TipsForBugReports and GetABacktrace.

Testing Done:
Ran `dev-server.sh` and verified contents look as intended.
