Open Badges - Bug Spotter

Over in the day job I'm working on Open Badges, a Mozilla thing, used to accredit informal learning and general usefulness.
The Open Badges use the metadata held in a .PNG to assert a credential, which is verified by the issuer (I think)
As a test I'm creating a set of badges for folk who submit bugs to me for our systems.
I'm probably going to have 3 levels of award, bug spotter, bug squasher and super spotter on something... Assuming I can get the Vagrant VM to start...
