Make changing window title a configurable option

[ardrabczyk]

I have plenty of these in my ~/.fluxbox/keys:

Mod4 x :exec wmctrl -a uxterm || uxterm
Mod4 e :exec wmctrl -a emacs@ || emacs
(...)

When I press Mod4-x fluxbox moves focus to an existing window titled
`uxterm' or it starts a new instance of uxterm if such window does not
exist. When mpsyt changes its window title automatically it breaks
this workflow. I have added a new config option called set_title
which enables/disables automatic changing of window title. It is set
to True by default for backward compatibility.

I think you should use WM_CLASS to identify uxterm instances, instead of the title. You can use the xprop command to find the value of this for a window, and it looks like it can be used in wmctrl with the -x argument.

So, try using wmctrl -x -a UXTerm.

Good idea, it works like charm. I have never thought about that,
thanks.

Now this patch is much less important but I think it's still valid.
Would you like to merge it or should I close it?

I think the PR should be closed, unless there is another reason to want this. Using WM_CLASS is the "correct" way to handle this. It is best to avoid adding too many configuration options to mpsyt.
