Various 1.6 updates - incomplete

liquids->fluids
pipes dont' have x,y,z any more, use getX() - they ask the underlyign
tile; this may make them less likely to crash if moved.

Forge ISided removed
ICareAboutTeleport wasn't being used, neither was ITeleport - both were
broken by BC api changes, and only tesseracts probably used them anyway
(IPipeEntry got rolled into IPipe)
WrenchClicked has lost some parameters
Pipes don't hold a world
sendChatToPlayer now needs a ChatMessageComponent
EntityPassiveItem, IPipeItem, andEntityData have been merged into
transport.TravelingItem

-  TileEntity tilePipe =
this.container.tileBuffer[ori.ordinal()].getTile();
+  TileEntity tilePipe = this.container.getTile(ori);

Various other changes as spotted.
Network code not compiling due to ant not setting up environment

TODO:
PipeLogic has be removed; the logic should be moved to the pipes.

Transport isn't needed; CRP should implement IPipeTransportItemsHook
