[Alpine-info] Instructions to configure XOAUTH2 in Gmail have changed

[Eduardo Chappa]

Dear Alpine users,

   with the upcoming change in gmail whereas username/passwords combination 
will stop working many users are attempting to configure Alpine woth 
XOAUTH2. Some users are reporting that the current directions fail with an 
error like

Authorization Error
Error 400: invalid_request

I expect to reply to many messages that report this error in the upcoming 
months. It seems that the solution to this error is the following:

   * Go back to the page where the user created the client-id and
     client-secret.

   * In the menu on the left, click on "OAuth Consent Screen"

   * In the page that appears, change the "Publishing status" to "Testing"

   * Below this, add the email addresses that will be allowed to login to
     Gmail under "Test Users"

It seems this is affecting users that are just creating client-ids and 
client-secrets, not users that already had them created. In my case, I hae 
Alpine published and do not have this issue (and for users that are having 
this issue, publishing the app does not fix the problem).

I hope this message will help some people find the information they need. 
I will be updating my directions in the web soon.

Thank you.
