Show current ticket price for an event

[karthikb351]

Since https://github.com/hasgeek/boxoffice/pull/167 has been merged (❤️ @shreyas-satish) we can specify the items_ids we want to render in the widget, and how to order them.

A side effect of this is that we can use boxoffice's /order/kharcha API to get the current price for a ticket and render it.

This will require us flagging a specific item id as the primary one, which is usually the most common ticket people may purchase.

I would say as an option to the most common item, the lowest price option (a one-day ticket) woudl allow us to say something like "tickets from X Rs."

That's a good point - but you'll still need to manual mark which item that is since t-shirts/workshops might be lower priced so we can't rely on just the cheapest's item.

True. I forgot that we might be separating out the add-ons (which makes so much sense).
