The final OB 1.0 specification changed the baking badges method
from tEXt to iTXt. Besides, the iTXt chunk should be a signed
assertion or the raw JSON (instead of the assertion URL).
This has been changed in order to make Moodle OB compliant.
Yuliya Bozhko, thanks for the patch! :-)
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
