When creating a new circle, the participants were not being displayed
after you click save and were sent to event.html.

The reason: event.html is a little hacked up. It displays people in the
circle.participants.both array, not the .receivers and .givers. array.

In app-CircleModule.js, the savecircle() function was not putting the
participants into the 'both' array, so they weren't showing up.
