Editor doesnt tell you you forgot to unsubcribe a event

[Barsonax]

Summary

It would be nice if the editor could tell you you forgot to unsubscribe a event somewhere as this can lead to very strange bugs if left unchecked.

How to reproduce

• Download EventNotUnsubscribed.zip
• Open duality restoring all packages and build the project.
• Open Scene, make sure its in 'Game View', enter sandbox mode and then click somewhere to trigger the MouseDown event
• Notice how the log will have 2 new entries that prints Scene: Data\Scene'.
• Exit Sandbox mode
• Reenter sandbox mode and click somewhere. Notice that we now have 4 new entries and sone of them are printing 'Scene: '. This is because Component1 now has a reference to some ghost copy of Component2 that lives outside of any scene. This is caused because the event is not unsubscribed.

If you want to redo this you have to close and reopen Duality to get out of the corrupted state.

Workaround

• Restart duality to fix the corrupted state.

There are some core events where Duality actually informs you about that, but this is only executed when reloading a plugin, not when exiting sandbox mode. Might need to take a closer look to figure out how to address this.
