Smoke particles should always be emitted straight up

[Alexey Torkhov]

Smoke particles when torch is wielded are emitted perpendicularly to it (I'm wondering why not parallel, but perhaps of 90° rotation I've set for it).
They should be emitted straight up not depending on torch current orientation. The simplest way do to it seems is to make custom point emitter that will emit particles with direction in world coordinates. The emitted will need to multiply direction by inverse of node orientation (mParent->mParentNode->_getDerivedOrientation().Inverse()).
