Add option to sort by "agony"#11

Agony being a combination of price, number of flights, long layovers and total travel time.

@Rafael Archuleta I added the ability to filter by Quality. You’ll find it in the Sort dropdown. Was that more or less what you had in mind?

Agony sounds funnier, but as long as the filter works based on the parameters I mentioned, I’ll be stoked. :)

lol it does. Quality is a combination of price, number of flights, long layovers and total travel time. So yes, it’ll do as you mentioned.
