Updates metadata in Badges 101 assertion file.

I swapped the badge criteria and issuer origin URLs in the assertion file generated for the Badges 101 badge, which are both heavily used for badge display. We should think about making this assertion file a model for others. Issuer Org was updated to MoFo, and version was updated to reflect the current badge spec version.

One thing not included in this pull request is a change to the issuer contact field -- I don't see it as particularly important, and wasn't sure if the current email address is real.
