EventManager/eventful: Pass building ID pointers to event handlers 

Previously, there was some disagreement over whether event handlers such as
Buildings::updateBuildings() took building pointers or building IDs shoved
into pointers. It turned out to be the latter, which, unfortunately, did not
compile on x64. Passing building IDs isn't possible in all cases, because
building event handlers can be called for recently-deleted buildings too.
Pointers to building IDs do work reliably, though.

Fixes #1003
