Allow Searching for Building-Name in Room

[rsommerfeld]

When trying to find a certain room (e.g. seminar room or printer), it would be useful to specify what building I want to find them in.

Pre-Context:

• Searching for a room with certain properties in a certain building.
• Rooms already have a connection to building (via. floor) and buildings have a name string.
• Relation matching is implemented in Show search results related to matches as additional matches #111 .

Post-Context:

• Buildings might become first-class search citiziens at some point (i.e. be searchable), but at this point there are no detail pages and hence it doesn't make sense to render buildings as search results.

Acceptance Criteria:

• The search query "seminar room main building" ranks a seminar room in the main building than other rooms and seminar rooms.
• When searching for "main building" rooms should be relational matches (i.e. the things in relation with the rooms would be 2 steps away from main building)
