All done, working, easy to add your own stuff to it.
But the code is pretty ugly.
Don't mind all the offset/rotation stuff (except eyeoffset, please pay attention to that) on the images, that's just because the modeller didn't align stuff properly, which, is no big deal because datablocks have the ability to fix that.

/acclist
Lists them all.
/equipacc Name
Equips one.
/unequipacc NameOrSlot
And unequips it.
May conflict with add-ons that use certain image slots.
coding:
Make your normal image, no item
AddAccessory(imageName,"AccessoryName",slot);
done
Doesn't check for any stupid coding errors that people might make.
Try not to execute your add-ons more than once.
Edit: P.S. someone take this script and make ears :3
