[114] Setup for Non-SQLite PDO Oauth2 sources failing

Added username and password to list of variables to return when setting up oauth2 authentication.

I'm not a "front-end guy", but I can see that the js code is merged and minimized, among other things, perhaps.  I'm not sure what else I need to do in order to get the fix in place there.  But, for the "clean" js, I believe this should be sufficient.
