Add WindowName option to FvwmButtons

[NsCDE]

Hi,

Today I have adapted "WindowName" FvwmButtons patch for FVWM3, together with man page entry.
I have been using it with FVWM2 for 1-2 years already.

This adds functionality for subpanels which intentionally have Title (like CDE Front Panel
and it's subpanels as you can guess) with non-ASCCI characters and spaces, which cannot be
accomplished with FvwmButtons module alias.

Hi @NsCDE,

This looks good. I'm note sure char windowname[128]; is necessarily long enough, but I suppose it will do for now. One suggestion:

diff --git a/modules/FvwmButtons/parse.c b/modules/FvwmButtons/parse.c

Removed unnecessary if (windowname ... and resubmitted.
