Event module small improvements

I would like a better looking ordering of the input boxes. For example, see the Add Booking Entry page. It has several input boxes on the same line, after each other. That looks better, and it saves space and prevents scrolling.

The Description box should be a bit larger.
The Hours per day box should be smaller, and you can show 8 as the default number.
The Materials language box can have English as the default text.
The Facilitators box should have the person who is adding the event as the default.

The label Date ('yyyy-MM-dd') is incorrect. It should be dd-mm-yyyy.
The default of End date coulrd be Start date + 1. (However, only when adding a new event, not when editing an existing event.)

Please change label Web site into Organizer website

In the overview of all events:

You can remove country name. The city name + country flag is enough information, and it saves space.
The wrapping of dates looks a bit ugly.
The Total hours column is wrong. You should not calculate total hours from begin and end date. For example: some facilitators organize 2 days of 8 hours, one week apart. That's 16 hours, not 7*8 = 56 hours!
