No indication which invitees accepted or declined on event's page

[ctrance]

@joshuaselsky @shaun965 - Looking at Event's page, I could not tell who accepted or declined the invite. Should we add that?

Next to each email address we will show:

• a green checkmark if the user accepted
• a red x if the user declined
• nothing if the user has not taken action

@shaun965 please see attached icons and let me know if you need anything else.
