Restoring bash history (experimental)

Enable feature with this option in .tmux.conf:

set -g @resurrect-save-bash-history 'on'

Bash history for individual panes will now be saved and restored. Due to technical limitations, this only works for panes which have no program running in foreground when saving. tmux-resurrect will send history write command to each such pane. To prevent these commands from being added to history themselves, add HISTCONTROL=ignoreboth to your .bashrc (this is set by default in Ubuntu).
