Search room by lecture

[octycs]

Is your feature request related to a problem? Please describe.
Mainly for tutorials, but also for lectures you will need to find out when and where they take place. So usually you have a tutorial, then look up its room on TUMonline and then look up its position. We could simplify this procedure if you could search for the tutorial right away in NavigaTUM.

Describe the solution you'd like
Integrate lecture names, tutorial groups, their times and location into the search. So if you search for a lecture/tutorial you can get a list of locations when and where it takes place.

Describe alternatives you've considered
If NavigaTUM is integrated in TUMonline, we might consider it not worth it.

Additional context
Related to #289 in that both are about integrating the schedule better. It is not a priority issue I think.

This would be duplicate functionality to TUMonline, so we should not bascially copy, but focus on providing a fast and easy way to get its time and location. That's why I think we should only add it to search, where the results indicate and link to the room, but not create or own pages for the lectures.
We would need to be careful about not collecting personal data (names of people etc.).
