making user definable variables really global

Hi,

I am struggling with the singular manual, and it appears that if there is
a my variable in the texi2html script, the value cannot be overwrited
by a required file (that is quite logical as the scope of the variable is 
then the script file). Thus I am going to remove lots of my for variables in
texi2html.init and make these variables global (which is hurting me 
inside, after all the my variables I did ;-).

If somebody knows a better approach I'd be glad to hear.
