API Restrictions Issue

[petertwise]

Currently Google API restrictions by IP are breaking the data fetch.

I think the issue is that file_get_contents doesn't send referer.
If instead of

$gcal_raw = file_get_contents($gcal_url);
$gcal_raw = json_decode($gcal_raw);

we do

$args = array(
      'headers' => array(
        'referer' => site_url()
      )
    );
$gcal_raw = wp_remote_get( $gcal_url, $args );
$gcal_raw = isset( $gcal_raw['body'] ) ? json_decode( $gcal_raw['body'] ) : array();

Then we should be able to keep the API restrictions
