Fully support self-signed certificates (and add debug levels)

Two unrelated changes:

1. Add full support for self-signed HTTPS certificates on the server

2. Add support for multiple log levels: So far we only use one, but
adding support for additional levels will help us tier the levels to
filter out excessive messages.
