Add pane synchronization status on right

[karnh]

Please add an indicator to show if all panes in window are synchronized or not. It helps a lot when multiple panes are open and you are switching between synchronized and unsynchronized mode.

I made following change to basic theme to make this work -
set -g status-right "#{?pane_synchronized, #[fg=yellow]SYNC #[fg=white]«#[default], } #H #[fg=white]« #[fg=yellow]%H:%M:%S #[fg=green]%d-%b-%y".

it looks like following -

@karnh This is implemented in PR #34 at the moment. If you could have a look to see what you think, that'd be great :)
