With the Persona provider now out of commission, no new connections to
the Mozilla openbackpack can be created. This patch adds an email
verification step to core to restore the openbackpack functionality.
It seems that CURLOPT_CONNECTTIMEOUT_MS is depdendent on the version
of curl compiled against. We don't need milliseconds here anyway, so
switch to the seconds value.
The badges feature allows to integrate Mozilla "Open Badges" to issue, assign,
manage and display digital badges in Moodle. This feature supports:
-- badge creation and issuing based on criteria
-- badge baking and verification service
-- direct pushing of internal badges to external backpack
-- interanl and external badge display in Moodle
-- Moodle block to display latest badges
