added new option to specify, on which screen

fluxbox should handle the windows. default behavior is to handle 
each available screen. closes #1159809. usage:

   -screen <"all"|int[,int]>

eg:  
    
    $> fluxbox -screen 0,2      will run fluxbox on 0.0 and 0.2 so 
                                one can run any other wm on 0.1. 

    $> fluxbox -screen all      default, fluxbox manages all screens
