* [Quest API] Add Instance Methods to Perl/Lua.
# Perl
- Add `quest::GetInstanceIDs(zone_name)`.
- Add `quest::GetInstanceIDsByCharID(zone_name, character_id)`.
- Add `quest::GetInstanceVersionByID(instance_id)`.
- Add `quest::GetInstanceZoneIDByID(instance_id)`.
# Lua
- Add `eq.get_instance_ids(zone_name)`.
- Add `eq.get_instance_ids_by_char_id(zone_name, character_id)`.
- Add `eq.get_instance_version_by_id(instance_id)`.
- Add `eq.get_instance_zone_id_by_id(instance_id)`.
# Notes
- The instance IDs methods return arrays of IDs for looping so you can check on mass the instances a player has for a zone.
- Keeps operators from having to guess which possible versions of a zone a player has an instance for or loop through them all to find out.
- Cleanup `common/database_instances.cpp` to mostly use repositories where possible.
* Update database.h
* Update character_corpses_repository.h
* [Commands] Cleanup #reloadzps Command.
- Cleanup messages and logic.
- Make reloading of zone points global instead of zone specific.
* Further cleanup.
- Add zone->GetZoneDescription().
- Add mob->GetTargetDescription(mob).
* Final cleanup.
* Typo.
