Make Spyder remember tab order

[gabrielclow]

With Spyder 3.2 we gained the ability to sort tabs on the Editor by dragging and dropping. I love this feature. The problem is that it doesn't remember the order I chose when I close and reopen. This makes this feature less useful because I have to sort it every time I open Spyder.

Thanks in advance.

@rlaverde, is this possible?

[rlaverde]

I'm not sure, I don't know how this data is saved/loaded when closing/opening spyder, I will try to address it with #4831

[ccordoba12]

Please don't. Leave this for another PR.

@rlaverde, is this possible?

It should be, but we will need a separate entry on the config for these

I'm testing and spyder remembers the tab order, files are saved and loaded in the tab order.

@gabrielclow could you give a reproducible example of when the file order changes?

[gabrielclow]

1. Open Spyder and have this tab order:
   
2. Do nothing, close Spyder, open again and now this tab order:
   
3. Do nothing, close Spyder, open again and once more, another tab order:
   

But there is more information: I tested some more and apparently this problem only happens when I have a project open. It looks like the problem does not occur when all projects are closed.

Good catch! This could be the source of the problem then.
