Problem with minified versions of angular and angular-resources:  The
problem is a 413 FULL HEAD error when you try to add to someone's list.
Looking in firebug and comparing the mobile (minified) version with the
web (non-minified) version, you can see the in the non-minified version,
'recipients' is [object Object] but in minified version, 'recipients' is
the toString version of the [object Object].

We can add to someone's list now but we have to use the non-minified
version of angular for the moment.
