Subject: [PATCH] oauth: Allow auth_url and token_url to be set in the config
 file

If set in the config file, these override the ones configured into the
remote.  This enables alternative oauth servers to be used for all
oauth remotes.  This can only be altered by editing the config file
for the moment.
