User can only add one guest to the Guests input box for a New Event

[Victor Thompson]

When adding a new event, regardless of how the user inputs the list of guests the string of text is used to describe 1 guest only.

To reproduce:
1. From any tab, expose the toolbar.
2. Tap the "New Event" icon
3. Fill in the event details and add the names of multiple guests, perhaps "Me, Bob, Jim, Frank" and save
4. Find that event in the Week view and select it
5. Note that under the heading "Guests" just one guest with the name entered in step #3 is listed.

Expected results: Either step #5 should list multiple guests or there needs to be a different way to enter multiple guests from the New Event view.

Current adding multiple guest via comma separated names is not supported, how to support multiple guest entry is currently undecided, we need design or spec for this.
