Correct console messages, comments, and some bugs

* Authentication confirmation doesn't happen at all on object construction. This routine is instead used to store the values for later usage. A call to a URL will show if there is a higher rate limit. In the newer dep `authorization` is calculated as well.
* Clean up and add existence checks in repoManager. Don't necessarily have to terminate the app if API Keys for GH aren't there... should just use lower rate limit... although other features might depend on those values. Appears to be part of the webhook but not confirmed.
