[PD] symbolatom: why does it not allow to type spaces?

It's nice to add those features, but by adding them to the pd-vanilla  
objects, that means patches written in desiredata are not compatible  
with pd-vanilla.

It seems a better solution would be to add new desiredata objects,  
then keep the iemguis compatible.
