xAPI Badges integration(Including references to badge assertions in Experience API activity streams)

Friends and Badgers, (CC: Credentials Community Group)

Andrew Downes, Jason Lewis, Ryan Smith and a few others have been doing 
some good work on defining how it might be possible to transport badges 
within xAPI "activity streams." (These streams are essentially collections 
of statements like "<entity> <verbed> <object>", or in this case, "Nate 
earned Badge #5" They have requested that the Open Badges specification 
host a couple definitions with our specification, so that distributed 
Learning Record Stores can reference our definitions of what badges are and 
what verbs are associated with badge activity.

See https://github.com/openbadges/openbadges-specification/pull/22 for an 
initial stab at making this happen. I'll be putting in a couple more 
updates when I have the chance to respond to some feedback from Andrew and 
Ryan, but I didn't want to hesitate any more before bringing this up before 
our specifiation group.
