New access token with refresh token does not seem to work

[uromahn]

I switched my installation to the headless auth process as described in issue #764.

It works now for me, however, after my access token expires, I am getting I/O errors with "broken pipe". The only way to get access again and remount my Google drive seems to delete the .gdfuse folder and then re-authenticate.

Question: is there an easier and probably more correct way to get a new access token using the refresh token? I simply haven't figured out how to do this? Maybe there is some scripting possible to accomplish this as part of a cron job?

Thank you!

P.S. Great tool. Thanks for building it.
