* Core/SmartScripts: SMART_ACTION_EQUIP prevent to false errors
* DB/Creatures: Added some data for dataless NPCs
* Core/Chat: Fix valid chat links being handled as invalid

Fix a case where valid chat links would have been handled as invalid.
This happened if these conditions were true:
- the link was a profession and the link name started with the same name of the profession, like spell id 61120 in esES locale "Inscripción de la tormenta de maestro" with profession name "Inscripción"
- the profession name was the same for more than 1 locale available, like esES and esMX, or enUS and enGB

* Core/Spells: fixed Throw Shield Visual and Clone Weapon
* Core/CrashHandler: Add more informations about locals
