Title: Include buildings in multi-selection tab for #1572

All buildings will receive the `?` thumbnail for now.

Currently showcases a slightly weird way of how we handle selecting buildings and units together: You cannot select both a unit and a building, and if you try to do so, the last selected entity always overwrites all previously selected ones of different type. This feels not right to me, but also probably won't be fixed in this PR.
