[TW275] - Core/Spells: Revert "Fix Death and Decay disappearing" and adds another way around it, by yesitsme

This reverts commit 8a9d7e26daf2445cc5914646602aff3292714721.
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

Restore memmove() instead of memcpy() wrongly replaced in 791130f6faf6294d2cb27bec409d7b4ee855243f , it's unsafe to use memcpy() with overlapping memory regions.
TW fix Slice and Dice

Will no longer put the caster in combat.
TW fix HAT and TTT

HAT will now have 1 sec cooldown and will no longer give other energy
users combopoints on their targets. Caster will no longer be put in
combat when a groupmember crits, and combopoints can now be gained on a
target which doesnt have any combopoints prior to the proc.
Turn the tables will no longer buff raid and party members.
