Consider Honouring ENV['OCTOPI_DEBUG'] for Tracing Pref

[runpaint]

We should probably respect an environment variable whose value is the type of tracing the user wants. This leaves the config files for permanent preferences, such as credentials, and frees client implementations from debug logic. IOW:

$ OCTOPI_DEBUG=curl some-client

To add to that, it would make the gem a lot cleaner if a user could also setup the project (repo) name in the github.yml file, or put all credential info including repo name as env variables. A rake task on the project to generate the yml file and place it in the config dir would simplify the process. Just my $.02.
