feat: Improved nodes events states

[marc2332]

Closes #849

Click events will only be emitted to elements that were previously pressed down (no need to register a mousedown event). Mouse leave events wont need a mouseenter or mouseevents to be registered in the nodes. Added a new mouseup event that behaves like the old onclick

This also cleans up a bit the internals.

I also made an exception for freya-testing so it can emit click events without the need of sending mousedown events before.
