Make All Views Detachable/Dockable and lay-out-able

[jamstruth]

Is your feature request related to a problem? Please describe.
It is frustrating to switch between the Scenes view, the Sprites view, the Palette editor etc. to perform actions when trying to build things concurrently (this is particularly annoying for palettes)

Describe the solution you'd like
Similar to any number of IDEs and Image editors I would like a way to have tabbed views of multiple objects open or multiple views with variable sizes to allow viewing and editing of files side-by-side. E.g. while colorising a scene I would like access to the palette editor so that I can adjust the palette

Describe alternatives you've considered
An ability to open multiple GB Studio windows for the same project at the same time and have them react to changes made in the other window could also work though is not as efficient

Additional context
