Minecraft Forge v1.3.4 changelog

Minecraft Forge v1.3.4
==============================
New: Exposed getters for NetServerHandler.playerEntity and NetworkManager.netHandler
New: Introuduced NetworkMod, a BaseMod extension and replacement for BaseModMP. All mods that are designed to work in the server environment should extend this.
New: Expanded the Mod check to test for missing mods and display a GUI screen for the client if it is missing any.
New: Implemented a generic EntityPlayer.openGui system, and the network backend for it to work on server and client. Mods should use this instead of MLMP's OpenGui
New: Added new Item.getIconIndex context sensitive version.
New: Added a new hook system for custom bows and arrows. See IArrowNockHandler and IArrowLooseHandler for details.

BugFix: Split mod_MinecraftForge so that Clients arnt required to have MLMP installed if they don't use a MP mod.
BugFix: Fixed up the Mac/Linux install scripts, removed the need for sed. Should fix some issues on OSX's without gsed.
BugFix: Fixed a bug that prevented tile entities from being updated if the block id did not change.
BugFix: Fixed a bug in update_patches that caused apostrphies to be removed.
BugFix: Fixed shearable blocks to use the current instance ID when dropping, making it behave better with subclasses.
BugFix: Deleted deprecated interfaces IUseItemFirst and IBlockSecondaryProperties
BugFix: Fixed ITextureprovider for multi-textured items when rendering on the GUI.

Misc: Marked forge packets as 'chunk' packets. Giving them a higher priority making the initial mod list check more reliable.

Misc: Ran AStyle over all Forge code
