Ability to detach the code editor from the main window

[mthreis]

Issue description:
It's a limitation of regular text editors (like VS Code or Atom): they can't reproduce Godot editor's functionality when it comes to auto-completion and/or syntax checking (for identation, for example). There doesn't seem to be a replacement for the code editor but, unfortunately, it's a chore to work with it since it takes too much screen space on the IDE, especially considering that there's a bar at the left corner that can't be minimized and a script list that can't be turned into tabs. Result: not too much room for what really matters, the code!

A possible solution would be adding a button next to the "distraction free mode" one that would detach the code editor from the main window, giving it one for itself. When the code editor is in a different window, the "Script" could or be removed or lead to that other window when clicked. The result would look somewhat like this:

There is already a few threads on the matter, #19197
