Subject: [PATCH] Exported GetSpellIDFromSlot into Perl

Exported the GetSpellIDFromSlot into Perl. Currently, there are numerous
Perl objections that can accept buff slot info, but nothing that can
return the buffs a mob/client currently has. This lets us iterate over
them with a loop, returning -1 if the slot requested doesn't exist.
