One might want to use the github debugging script with GitHub
apps. Add that as a possibility.
This also piggybacks a small fix where we called getGithubClient with
the wrong data type.
The github debugging tool proved to be quite useful for prototyping
new stuff using the github api. In the process I ended up copying half
of the GithubConnection into it. However for trying out new stuff it
would be great to implement and try out the features/fixes directly in
the Github driver.
And here it is! The script now starts up a standalone version of the
Github driver which can be used to query and debug isolated stuff
