Notes:

Returns:

Example:

local BL = B:GetLookupTable()
assert(BL["Some english word"] == "Some localized word")
DoSomething(BL["Some english word that doesn't exist"]) -- warning!

Notes:
* If you try to access a nonexistent key, it will return nil.
* This is useful for checking if the base (English) table has a key, even if the localized one does not have it registered.
