Use pane_id instead of pane_index to identify a pane since the latter can change after a pane is created.

[vitillo]

By using pane_id instead of pane_index it is possible to open a pane through vimux and successively open/close new panes through tmux while continuing to send keys via vimux only to the original pane.

How far back does pane_id support go in tmux? I think this makes a lot of sense but I want to try and support tmux 1.6 and up.

[vitillo]

A grep of the 1.6 sources seems to confirm that pane_id is supported. I didn't try to run it though.

this would also allow you to run commands in a pane which isn't visible, like if you have vim pane zoomed, correct?

[vitillo]

That doesn't work; I did not investigate further but I guess it shouldn't be too difficult to add this feature once panes are identified through pane_id.

[ersatzryan]

I haven't been able to send-keys to a pane that is hidden because of a zoomed pane, so I am not sure it it will be possible

[stellarhoof]

We could salvage the variable naming changes since #110 covers the same functionality and more.

Thanks for this contribution @vitillo. I'm sorry you didn't get credited with it in the history quite right, but this did eventually get merged (albeit belatedly) via the refactored version of this in PR #110.
