(cherrypicked from e1f14215d8)
* Mostly aimed at removing Log/DatabaseEnv includes from other headers
* Fix most packet headers including other packet headers - moved common structures such as ItemInstance to their own files
* Moved SAI function definitions to source files (massive or requiring many different dependencies)
- .debug hostil now shows spawn ID (DBGUID) in addition to current GUID (so you can .go creature to it)
- .npc temp now takes an additional argument before the creature entry that determines whether the spawned creature instantly despawns upon death. Default is instant despawn (current behavior).
- Add .npc evade command.
- Add .pet level command.
- .server shutdown and .server restart now fail with an error message if time is below a config var (GM.ForceShutdownThreshold, default 30s) as long as another player is connected.
- New commands .server shutdown force and .server restart force bypass this limitation.
