Application-wide event bus

[lukashornych]

There are already some places where a application-wide event bus for notifying unrelated components about changes (similar to Spring Framework ApplicationEvents). Neither JS nor Vue provide this out of the box, however there are libraries that provide such functionality.

I would like to analyze if it would be something that would help decouple some components. For example, I would like to decouple:

• window list from keymap / subject path
• creating new tabs from workspace service call (not sure if it would help anything though)
