[regression] cant select multiple buildings

[stheid]

In previous versions i was able to select additional buildings for simulation by just clicking at them. Now i can only select one simulation and all other buildings remain in this brownish tint and are not simulated.

Hi @stheid - we decided to remove this feature because of these two arguments:

• we often saw people struggling with the user interface and wanted to make it more simple. Sometimes people selected second buildings by mistake (especially on touch devices).
• it was a feature that was strongly coupled into the code base - when building new features it often interfered with this feature. For example, simulating a new building needs a new center of simulation, needs to retrieve new vegetation data (if available) and so on.

In the end we thought that the "select multiple buildings" was not such a good feature to justify these disadvantages.
