Update to Lemur Rental Box

After the usual pestering by Sylvie Etoile, I added several new features to the Lemur Rental Box System and I must say this product is getting really robust after all the added features.

The new features include:

1. Rental box displays late texture and how much time the renter is late
2. In Late Mode, when renter pays, the rental box takes into account payments for late days.
3. Anyone can now pay for renter when rental box is in rented mode.

To be honest, the vast majority of sales come from the sick toys of the Depraved Monkey, but it still feels good when people use the rental box because this product once kept us afloat when we first started last year.
