* [LUA] Add Zone and Language Constants
This will add Zone:
```lua
if eq.get_zone_id() == Zone.Qeynos then
foo()
end
```
It will also add Language:
```lua
if e.language == Language.ElderElvish and e.other:GetLanguageSkill(Language.ElderElvish) >= 100 then
e.self:Say("You know my language!", Language.ElderElvish);
end
```
These changes should help avoid magic numbers in quests and aide in readability without the need for -- comments to clarify.
* Adjust to lower case
This should prevent any optimizations being done on the "1 char string"
This also fully documents the packet and expands the uses of
quest::say/QuestSay
