Bug fix #2411

(Looks like big commit, but is mostly just change of API call!)

Particle emittors now can be parented to an armature Bone, and give the
correct path for each particle. Note that this doesn't work for deform!
And, for each particle the entire armature is evaluated, all actions and
NLA strips.

It used to work a little while BTW, but the code just called ALL armatures
and made ALL deforms again. Was quite slow... thats why the API call
change: do_all_actions() now accepts Object * to only do that one. With
a NULL it now does all still. Will disapppear in recode of course...
