* [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.
- #guild rename was checking argument count and not allowing you to rename guilds to names that had spaces.
- #killallnpcs was crashing zones when used sometimes due to getting a nullptr somewhere in the loop.
- #worldwide message was using just the first word of the message sent using the command, not all of them.
- Cleanup messages and logic.
- Adds GetGuildNameByID, GetGuildRankName, GetGuildIDByCharacterID, and IsCharacterInGuild helper methods for guild stuff.
- Convert #guild info message to a popup display to tidy it up and make it more legible.
