UNIT_SPELLCAST_SUCCEEDED and multiple results

[doofus]

Yes the "normal" Frostbolt is 116 and the subsequent event when the missile reaches the target is 228597. Since I only care about having cast the spell, and which spell, it is the first event which is of value.

I was hoping to find a better way of detecting "have I cast a spell successfully? and which spell?" rather than "has the missile travelled to the target and did it hit or miss?".

Of course I have filtered out the spells I do not care about, in this case 228597 and I hope they do not change the IDs ...
