Window names are no longer dynamic after restore

[frontierpsycho]

I started using tmux-resurrect recently, and I really like it, but I seem to have a problem with window names.

Before I started using tmux-resurrect, window names would be updated based what was running in them at the time. When working on a resurrected session, however, the names of the resurrected windows never change: If I run vim on one of them, the name is still bash. If I quit vim on one that was already called vim (because it was running vim when I saved the session), its name keeps being vim.

Thanks for bringing this up..
In man tmux, the description for automatic-rename pretty clearly hints why this is happening:

This flag is automatically disabled for an individual window when a name is specified at creation with new-window or new-session...

When restoring the window, we are specifying it's name.. so that disables automatic rename.

Here's the possible high-level solution:

• when doing a save, for each window also save its automatic-rename value.
  
  There does not seem to be FORMAT flag for this option so we'd have to manually iterate over windows and call tmux show-window-option -t "session_name:window_number" automatic-rename to see if it's on or off (or nothing, in which case global option is respected).
• when doing a restore, do *not* restore window name if automatic-rename is on.
  
  This should be the easier step as it's just a simple if..else for 2 lines: here and here.

@frontierpsycho how do you feel about making a PR for this?
I'd be glad to help you with questions and anywhere you get stuck...

Another simpler solution:
We might as well just not restore window names if global automatic-rename is on. Window names will be restored automatically.

The downside of this solution is: if a user manually names one of the windows, that name won't get restored...

I don't think I would have enough time to make a PR, unfortunately :) I am not at all familiar with the inner workings of tmux, and it would take me a lot of time.

I like the first solution more, though.

Also, I see it's just bash scripting, after all. But still, I'm not sure I could spend the time, now. I'll let you know if that changes.

Created a workaround to enable automatic-rename on all tmux windows
