Added option to add custom window title extension

[Krzmbrzl]

In #4153 it was requested to have an option that allows to customize the
window title in order to better differentiate between the windows of
multiple Mumble instances.

This commit allows just that by letting the user specify a postfix
that'll be appended to the window title.

Fixes #4153

| Added --window-title-ext to set a custom window title extension

--post-title

I would prefer --window-title, it's self-explanatory. --post-title sounds more like the title of a (blog) post. Also not everybody might understand what a "custom window title postfix" is.

It's not. Actually it's even misleading. This is why I didn't use it.
This option does not allow you to specify a window title. It allows you to set a postfix string that'll be appended to the window title.

That could happen, yes... Any suggestion for a better explanation?
IN the worst case though I think people can simply try it out and see what it does ^^

I wouldn't call it misleading, but better slightly misleading than incomprehensible at first sight.

This option does not allow you to specify a window title. It allows you to set a postfix string that'll be appended to the window title.

I still would have to try it to see what that means. I also wouldn't mind if it really would set the complete window title, without any prefix. If a user wants Mumble in the title, they could still include it.

--window-title
Set "Mumble -- " as the window title.

@streaps what do you think about --title-extension (or --window-title-ext) with the description Sets a custom window title extension?

[streaps]

Both are fine. I'm undecided, which I would prefer :).

--window-title-ext

Is the best choice imo, thanks for choosing that 👍
