<pre style='white-space:pre-wrap;width:81ex'>Fix Ragnaros melee behaviour

* Ragnaros will now have a proper melee combat behaviour:
- if his main target (victim) is in melee range, he will attack it and
proc Elemental Fire on it
- if his main target is out of melee range, he will pick another target
in melee range and attack it and proc Elemental Fire
- if there is no target in melee range, he will cast Magma Blast on a
random target until someone comes in melee range
- Simplify initial code, thanks @killerwife for his suggestions

* Fix the way adds from Phase 2 are counted: each was counted twice on
summoned with the previous code</pre>
