Currently the github auth token has to be copy/pasted in an input field at "Manage Jenkins" -> "Configure System". Because of this an already created token can't be reused. Github doesn't show used tokens and Jenkins doesn't show its credentials content. It can also be seen as a security risk that an access token is exposed in that screen.

I would be great if this plugin can use Jenkins Credentials to set the token or even use the setting from the GitHub Plugin. I imagine everybody who want to use this plugin has the GitHub Plugin already setup.
