New server-only EO data file formats


Conventions:
	Record*   refers to an arbitrary number of repeating instances of a data structure
	Record*n  refers to a known number of repeating instances of a data structure
	(string)  format is a single length byte followed by that many bytes.


--------------------
din001.eid - [EID] Endless Inn Data (Inn/Citizenship/Home info)
--------------------

Semantics:
	Each Record corresponds to a possible home location that a character can belong to.

	Innkeeper NPCs with a matching vendor ID will allow you to subscribe/unsubscribe to
	that home location, as well as let you stay in the inn for a hard-coded price.

	When unsubscribing from a home location, the home location is reset to #1.

Data Format:
	"EID" (3 bytes) (fixed string)
	Record* (repeated until end of file is reached)
	{
		ID (2 bytes) - Corresponds to NPC vendor ID
		Name (string) - Home string displayed on paperdoll
		SpawnMap (2 bytes) - Map teleported to after dying
		SpawnX (1 byte)
		SpawnY (1 byte)
		InnSleepMap (2 bytes) - Map teleported to when sleeping at the inn
		InnSleepX (1 byte)
		InnSleepY (1 byte)
		AltSpawnEnabled (1 byte) - Boolean value if AltSpawnMap/X/Y is used when above a hard-coded level
		AltSpawnMap (2 bytes) - Map teleported to after dying when above a hard-coded level
		AltSpawnX (1 byte)
		AltSpawnY (1 byte)
		Question1 (string) - Questions/answers for citizenship test
		Answer1 (string)
		Question2 (string)
		Answer2 (string)
		Question3 (string)
		Answer3 (string)
	}


--------------------
dtd001.edf - [EDF] Endless Drop File (NPC item drops)
--------------------

Semantics:
	On NPC death, the drop table is read top to bottom, a uniform random number generated
	for each item on the list. If the random number generated is lower the drop chance value,
	another uniform random number is picked between MinAmt and MaxAmt to determine the amount,
	that amount of the item given by ItemID is dropped, and the table is not read any further.

Data Format:
	"EDF" (3 bytes) (fixed string)
	Record* (repeated until end of file is reached)
	{
		ID (2 bytes) - Corresponds to NPC ID
		NumDrops (2 bytes) - Number of items dropped
		
		DropRecord*NumDrops
		{
			ItemID (2 bytes) - Corresponds to Item ID
			MinAmt (3 bytes) - Minimum amount of item dropped
			MaxAmt (3 bytes) - Maximum amount of item dropped (may be equal to MinAmt)
			DropRate (2 bytes) - Chance (x in 64,000) of the item being recieved
		}
	}


--------------------
dts001.esf - [ESF] Endless Shop File (NPC shop/crafts)
--------------------

Semantics:
	NPCs allow purchasing between 1 and MaxAmt of an item from their shop at BuyPrice each,
	or selling of any number of an item at SellPrice each. Crafts require all of their
	ingredients in the required amounts to create a given item.

Data Format:
	"ESF" (3 bytes) (fixed string)
	Record* (repeated until end of file is reached)
	{
		ID (2 bytes) - Corresponds to NPC vendor ID
		Name (string) - Name of store

		Unknown (3 bytes) - Unknown data! (Always the raw bytes: 01 FB 01?)
		
		NumShops (2 bytes) - Number of items with buy/sell information
		NumCrafts (1 byte) - Number of items that can be crafted
		
		ShopRecord*NumShops
		{
			ItemID (2 bytes) - Corresponds to Item ID of the item to be bought/sold
			BuyPrice (3 bytes) - Price the shop will sell an item for each
			SellPrice (3 bytes) - Price the shop will pay per item
			MaxAmt (1 byte) - Maximum number of items that can be bought per transaction
		}
		
		CraftRecord*NumCrafts
		{
			ItemID (2 bytes) - Corresponds to Item ID of the item to be crafted
			Ingredient1ID (2 bytes) - Ingredient item ID/amounts required to craft the item
			Ingredient1Amt (1 byte)     or 0 if fewer items needed.
			Ingredient2ID (2 bytes)
			Ingredient2Amt (1 byte)
			Ingredient3ID (2 bytes)
			Ingredient3Amt (1 byte)
			Ingredient4ID (2 bytes)
			Ingredient4Amt (1 byte)
		}
	}

dsm001.emf - [EMF] Endless Master File (Skill masters)

	Record*
	{
		ID (2 bytes) - Corresponds to NPC vendor ID
		Name (string) - Name of store

		Unknown (3 bytes) - Unknown data! (Always the raw bytes: 01 FB 01?)

		NumSkills (2 bytes) - Number of skills the master teaches

		SkillRecord*NumSkills
		{
			SkillID (2 bytes) - Corresponds to Spell ID of the spell to be taught
			LevelReq (1 byte) - Level required to learn the skill
			ClassReq (1 byte) - Class ID required to learn the skill
			Price (4 bytes) - Cost to learn the skill
			SkillReq1 (2 bytes) - Spell ID of skills required to learn the skill
			SkillReq2 (2 bytes)     or 0 if fewer skills needed
			SkillReq3 (2 bytes)
			SkillReq4 (2 bytes)
			StrReq (2 bytes) - Minimum stats required to learn the skill
			IntReq (2 bytes)
			WisReq (2 bytes)

	Record*
	{
		ID (2 bytes) - Corresponds to NPC ID

		Rate (1 byte) - Rate of NPC messages
