Add tag for "free" events

[ckenst]

Is there an icon or tag we could use to highlight free events? Of course we'd need to define what free meant. Often workshops don't have a conference fee but might charge a small fee to help reserve a room, etc.

I doubt there's anything free free. We could however define "very cheap" or "almost free" as anything under 100 dollars/euro. Using green colour for those events or adding a green exclamation mark or "i" in front might suffice probably.

That's what I was thinking -> under $100/euro. I believe most workshops only charge a deposit, but not an actual entrance fee. This is low on the priority list though.
