Added plugin for the window option "Synchronize panes"

[JannoTjarks]

Hi guys,

i added a plugin for your tmux theme. It's called "synchronize panes" because it gives me in the rigth status bar an info whether the window option synchronize panes (:setw synchronize panes) is on or off.

I added an info to the README.md and INSTALL.md already. Maybe you have an idea for a better infotext. At the moment the label is called "Sync" in default and the value is "on" or "off". The label is customizable for the enduser in the .tmux.conf.

I hope the code meets your requirements!

This is cool, but why would someone need this?

[JannoTjarks]

Often I use the synchronize panes option to configure cisco switches & router which need/have the same configuration (a port-channel on a vpc cluster as example) or to work on redundant linux clusters. Most time i have multiple windows open and need to know if synchronize panes is set in the current window. Other people are adding a color to the status bar: https://blog.jpalardy.com/posts/tmux-synchronized-panes/

I see, I misunderstood before hand. I can actually see how this can be very helpful. I'll do a code review soon.

Code LGTM, but we're going to have to clean up the commits. Otherwise, looks great and I look forward to using this feature. I would also like to get it merged in by tomorrow so we can give you credit for hacktoberfest.

That sounds great! Thank you!

Could you squash the commits?

[JannoTjarks]

I squashed the commits. Now there is only one.

Bump :-) I would also benefit from this niche-but-amazing use case
