Memory leaks, performance issues across core

Description

I've done some profiling and found some issues around many common code paths, which affect every user.

While I don't currently have exact numbers, the memory gains should be significant, especially during long editing sessions, ranging from few hundred megabytes to possibly gigabytes. Also, many listeners were left registered after deleted layers, thousands of them.

There are also some performance issues; funniest for me, the selection performance is held back by the conflict manager panel, which checks every object, even when there is no conflict. Only if the panel is visible.

I'll be publishing the patch soon as well.
