Updates Particle System on an object by hitting the Update button,
regardless the object is selected or not. The object must be named
“Particle Object”, the script can auto name the object of your choice
with that name by hitting Set while the object is selected.
It´s very usefull when adjusting force fields and you have to constantly
switch to the particle emitter just to hit the update button. Now it´s
just a matter of hitting a button and voila, everything gets recalculated and
you can keep making adjustments to the force fields.
