[Shaman][Elemental] Echo of the Elements Visual

[norbert.pls]

WoW Freakz spell link: Echo / Lava Burst / Lightning Bolt / Elemental Blast / Mastery: Overload
Bug description: Lightning Bolt, Elemental Blast and their Overloads, do not have a visual when duplicated by Echo of the Elements

Lava burst has the visuals, however, the damage of the echo lands when the initial spell hits the target, not when the echo hits it.
