Reasons: 1) Update of [API::Google](https://metacpan.org/pod/API::Google) lib: now it supports auto refresh of access_token 2) `$api`, `$user` and `$dtf` are unavailable from other packages. I suggest to use ``has`` from [Mojo::Base](https://metacpan.org/pod/Mojo::Base#has)
Reasons:
$api,$userand$dtfare unavailable from other packages. I suggest to usehasfrom Mojo::Base
