This function is used in many scripts to find the nearest enemy within the given distance.
However, it had an implicit limit to the ATTACK_DISTANCE. so in many case the "dist" was in fact just ignored.
In other case, the ATTACK_DISTANCE is required. So 2 functions are necessary to avoid ambiguities.
The refactoring is the split of the function in 2: SelectNearestTarget and SelectNearestTargetInAttackDistance.

* Change system logic - unify Auras, AreaAuras and PersistentAreaAuras:
* Aura has now its owner - which is the WorldObject, which applies aura (creates AuraApplication object) dependant on aura radius, and effect type
* Owner can be Dynobj (DynObjAura class) for PersistentAreaAuras, or Unit (UnitAura class) for Area and nonArea auras
* Aura data is shared for all units which have AuraApplication of the Aura
* Because of that AuraEffect handlers , and periodic tick functions can't modify AuraEffect object (they are const now)
* Remove spell source and AreaAuraEffect classes
* Add AuraEffect::UpdatePeriodic function, to allow periodic aura object modification (target independant)
* Add AuraEffect::CalculateAmount and AuraEffect::CalculateSpellMod function, to allow non-default amount calculation
* AreaAura updates are done in owner _UpdateSpells cycle
* Since now you don't need to wait an aura update cycle to get area aura applied on it's correct target list
* And you can access area aura target list
* Add basic support for aura amount recalculation
* Save recalculation state and base amount of auras to db
* Add AuraEffect::CalculatePeriodic function to determine if aura is periodic, and to set correct tick number after aura is loaded from db
* Add ChangeAmount function in addition to SetAmount function, to allow easy reapplication of AuraEffect handlers on all targets
* Sort aura effect handlers in SpellAuras.cpp and .h by their use
* Add check for already existing aura of that type to some AuraEffect handlers, to prevent incorrect effect removal
* SPELL_AURA_CONVERT_RUNE and MOD_POWER_REGEN and MOD_REGEN hacky handlers are now implemented correctly
* Send aura application client update only once per unit update - prevent unnecesary packet spam
* Fix ByteBuffer::appendPackGUID function - it added additionall 0s at the end of the packet
* Fix memory leak at player creation (not deleted auras)
* Updated some naming conventions (too many to mention)
* Added Unit::GetAuraOfRankedSpell() function
* Remove procflags on aura remove, use Aura::HandleAuraSpecificMods instead
* Added functions to maintain owned auras (GetOwnedAuras, GetOwnedAura, RemoveOwnedAura, etc)
* Implement AURA_INTERRUPT_FLAG_LANDING
* Implement EffectPlayerNotification (thanks to Spp)
* Remove wrong aura 304 handler
* Add better handler for death runes
* Remove unnecesary variables from DynamicObject class, and cleanup related code, link dynobj duration with aura
* Add GetAuraEffectTriggerTarget function in CreatureAi for special target selection for periodic trigger auras used in a script
* Add many assert() procection from idiots using some functions in wrong way
* I am to lazy to write here anything more
Thanks to Visagalis for testing this patch
