Update hello_effects.adoc

Fixed broken new lines.
Set emitter parameters table column widths to 15,45,15,25 to give more space to second column to allow for alignment of third column content. May need to adjust once more.
Removed un-needed horizontal rule.

 As you see in the debris example, texture animations improve effects because each “flame or “piece of debris now looks different. Also think of electric or magic effects, where you can create very interesting animations by using an ordered morphing series of lightning bolts; or flying leaves or snow flakes, for instance.
