[0663] Added day/night switch to equipment of creatures 68 & 1976

* Made patrolling guards (creature 68 - Stormwind City Guard and
creature 1976 - Stormwind City Patroller) in Stormwind swap their
equipment at nightfall. They will now wield a lantern instead of their
sword.
* Removed creature addon as they were strictly equal to creature
template addon
* Made creature 1976 (Stormwind City Patroller) use sword+shield
equipment by default they were previously using lantern+shield
* Fixed current and added missing equipment data to make creature 1976
(Stormwind City Patroller) and wandering creatures 68 (Stormwind City
Guard) use lanterns during the Night event. Static creatures 68
(Stormwind City Guard) still wield their sword
[0664] Reworked Pyrewood Village event

* Moved Pyrewood Village event from game_event_creature to
game_event_creature_data to reduce data redundancy:
- Removed 'Pyrewood Village - Day' event: human NPC will be spawned by
default
- Moved 'Pyrewood Village - Curse of the Worgen' event id to decrease
core memory usage
- Removed all addon, waypoints and spawns of Moonrage worgens
- Cleaned all forced models ID
- Made all Pyrewood Watcher, Sentry, Elder, Armorer, Tailor and
Leatherworker transform into their worgen equivalent at nightfall
