[Proposal] Add function to save multiple editor layouts

[varkatope]

I like that the editor panels can now be moved around in 0.9, though the size of the Library panel doesn't seem to save correctly for some reason. With the ability to move panels and activate/deactivate them, and the possibility of there being more panels in the future, it would be nice to be able to save multiple different layouts depending on our workflow. Maybe there could also be a function to easily revert to the saved layout in case we've moved things around during work, or possibly a way to save the editor layout with the material .ptex project file if possible.

Hmm I think saving the layout with the .ptex file is not a good idea since several .ptex files can be open at the same time.
But being able to save and restore layouts is definitely a nice feature for next release.

@RodZill4 Ah yeah, that makes sense about not saving to the .ptex file. Saving/restoring global layouts is more elegant anyway.
