Swipe between weeks on the booking page

When customers pick a day, they can now drag the week sideways: the days follow their finger and slide to the next or the previous week. The arrows beside it are bigger and easier to tap on a phone.

• Drag left for the next week, right for the one before; a short drag springs back
• At this week and at the last day you take bookings, the days give a little and spring back, so it's clear there's no further
• The arrows and a two-finger swipe on a trackpad slide the week the same way
