F2F Challenges let you set multiple prizes, but only the first one is actually used

[mtwomey]

Should limit the user to only 1 prize on F2F challenges.

[vikasrohit]

We do restrict the number of prizes for Tasks, if we need to restrict it for F2F, we can do that as well. fyi @acshields

[acshields]

@vikasrohit - adding this to the December backlog.

[vikasrohit]

Ok @acshields but from requirement standpoint, we do want to let only 1 prize for the F2F, right?

[acshields]

Yes @vikasrohit - confirmed that there should be 1 prize for F2F.

[vikasrohit]

@acshields moving it to current release to clear number of small issues from the list.
