RE: [ENG/ITA] SplinterRoi: Do You Like Icons? I do!

I need to add a sort of FAQ to explain that, because I know it's not very intuitive: basically "long" is for cards that are being rented for 14 days or more; "medium" 13-11 days; "short" 10-8 days (as 8 days is the current minimum length for a rental).

The idea is that if you choose "long" you see cards that are rented from the start of the season, "medium" cards that are rented after a few days from the season's start, and "short" cards that are rented only close to the start of the last week of the season.

And when the site shows you see rental ROI, that is estimated according to the selected length: for ex., "medium" has a 4/5 multiplier and "short" a 3/5 one.
