Add Support for Pane Title

[mehar]

windows:

• w1:
  panes:
  - pane_title:
  - ls
  - pwd
  - git status

If the pane yml is a Hash, then we can set the pane_title variable, which in turn can be used in "pane_border_format"

Ex: setw -g pane-border-format " [#{pane_index}:#{pane_title}#{?pane_synchronized, SYNC,}] #{pane_current_command} "

Very cool, would also like this.
Allows one to fix all the panes named with unhelpful (from an ID standpoint) wrapper commands like ssh.

Thanks @bedge

@ethagnawl This would be a really useful feature. Can this be merged please?

Hi, @mehar. Apologies for the delay on this.

I've pulled your changes and done some poking around. Does this actually set the pane title? When trying to do so, I see:

tmux: unknown option -- T
usage: select-pane [-DdegLlMmRU] [-P style] [-t target-pane]

[mehar]

@ethagnawl let me check

That codeclimate failure is annoying. Does anyone have any ideas for a simple solution? (Ideally, something other than just reverting my changes.)

[ethagnawl]

@mehar Were you ever able to verify that this is working as expected?

[woodgear]

is there some update here?

[ethagnawl]

@mehar Any updates on this? Also, is the pane title set by the config option likely to be overwritten by tmux when the user does something which causes tmux to change the pane_title value?

[ethagnawl]

While this approach does work initially, the pane title is not persistent.

I think a better way forward would be to use a user provided variable and pane-border-format.

Thank you for the contribution @mehar and I'm sorry that this PR languished for so long.
