[PD-dev] getting the classname in an class

[Hans-Christoph Steiner]

I think this should be part of the standard save mechanism, so I just  
committed the change to a bunch of externals.  I didn't touch  
externals/iem since I know you guys like to handle stuff yourself.   
It actually makes sense like this (from entry.c):

static void entry_save(t_gobj *z, t_binbuf *b)
{
     t_entry *x = (t_entry *)z;

     binbuf_addv(b, "ssiisiiss", gensym("#X"),gensym("obj"),
                     x->x_obj.te_xpix, x->x_obj.te_ypix,
                    atom_getsymbol(binbuf_getvec(x->x_obj.te_binbuf)),
                    x->x_width, x->x_height, x->x_bgcolour, x- 
 >x_fgcolour);
     binbuf_addv(b, ";");
}

Perhaps atom_getsymbol(binbuf_getvec(x->x_obj.te_binbuf)) could be  
defined in m_pd.h as something like "class_getclassname"

Terrorism is not an enemy.  It cannot be defeated.  It's a tactic.   
It's about as sensible to say we declare war on night attacks and  
expect we're going to win that war.  We're not going to win the war  
on terrorism.        - retired U.S. Army general, William Odom
