Scheduling dialogue: print avail. rooms

In the 2017 version totals lines, for instance, have already been shown in the scheduling dialogue. If a requested room or one of the alternative rooms is available, the cell on the respective place in the time grid is coloured in green. As of Untis 2018 the cell also shows how many of the respective rooms are available. If there are, for instance, 5 rooms in a ring of alternative rooms and 2 are not available, the totals line will show 3/5 since 3 out of the 5 rooms are available at the requested time.
