Godot: Seperate node dock into dedicated signal and group docks

[TheDuriel]

Godot version:

3.1

This reduces the number of clicks required to edit either by one when the previous tab was in focus.

On the upside it would allow renaming the "node" dock to something more descriptive and useful. On the down side it would add another unclosable dock to an interface that can already have 7 different types of sub-windows (including things like debugger) at the same time. I think this is a good idea, but the editor layout has to become much more customizable (like the ability to open or close certain docks altogether, more ways to stack things on top of each other, expand and contract. etc.) before it can support additional docks.

@TicklesTheBrain Docks already occupy Tabs in one of the 8 slots. Separating the Node dock in to two would not take any additional space, they'd just be Tabs of their Container.

[TicklesTheBrain]

Sure, but an additional tab label is still clutter in an already cluttered workspace.

@TicklesTheBrain What purpose does it serve to hide information within a sub-menu? An additional dock would not clutter the editor, since both of them still could be stacked in a slot.
