Frontend / Appointment tables: Show same date information in email as after click of booking button

[Theophilix]

The date information in the confirmation email is not precise. Only the beginning (not the end!) is listed and with slashes.

We should change this and use the same date information in email as after click of booking button (sorry, wrong order here)

This could lead to problems with "{date}" and "{time}" variable. For example, the sentence "your appointment is at {time} on {date}".
So we need a new variable {datetimelist}. This variable displays what we have in confirmation message after clicking the button (see second screenshot)

Fixed in 4.7.4 version.
