In order to support multi-worlds such as MultiVerse, the server needs the
ability to register dimensions on client or many forge mods such as IC2
will not function correctly. This has been an issue for MCPC which
provides both Forge and Bukkit support to players. By adding the
DimensionRegisterPacket class, MCPC now has the ability to send the
required packet to client to register a dimension with DimensionManager.
An issue with biome adding mods which is becoming increasingly annoying for players, is that many mod authors that add biome specific world generation or mobs in their mods, for the most part, hard code them to work with vanilla biomes only. This becomes a huge problem when it's difficult to even find a vanilla biome, let alone a specific one, when biome mods are installed.
A simple solution to this problem is a tag system for biomes that allows mod authors to set up their world generators, or mobs to generate or spawn in biomes that have been registered with a specific tag such as "FOREST", or "FROZEN". I wrote such a system a few months ago, which I've been using with my own mods, and have made available to anyone who wants to use it. Since then, I've had requests from mod authors and players alike to try and get it, or at least similar functionality, into Forge, where other mod authors will be more comfortable using it.
Aside from the tags, it also includes a rule based system to classify biomes that have not already been registered with it when information is requested on them (You can opt out of this by registering a biome as type "NULL"). And additionally, the ability to register IWorldGenerators for specific biomes, or biome types (tags) to speed up chunk generation a little bit.
Added an event on potion ingredient applied. Event contains the item
stacks of each of the potions being brewed as well as any remaining
ingredients.
Changed TileEntityBrewingStand and SlotBrewingStandPotion to look for
instanceof ItemPotion rather than potion.itemID
Adds IExtendedEntityProperties interface, which specifies three methods
that are needed: Init, Save, and Load.
Adds the EntityConstructing event, which is called during the
constructor of Entity. It is needed there so that the reference is in
place during the ReadNBT call.
Adds hooks into Entity that allow registration of
IExtendedEntityProperties classes, as well as saving and loading to NBT.
