Incorrect CC API implementation for getPeripheral()

Since at least 2.0.2, the mod reports a different object for each side of a peripheral while the CC API expects the same object returned for all faces of that object.
See initial logs from #88 about this: when placing a second computer, there's extra attach & detach events popping up. Here's logs from my mod, then from that build of SGCraft:

SGCraft implementation of getPeripheral should cache previously created interfaces, or, just use the TileEntity itself as an interface or storage of the latest.
For reference, getPeripheral() is called from the main thread so the World.getTileEntity() call is safe.

According to this: https://github.com/AlmuraDev/SGCraft/blob/master/src/mod/gcewing/sg/features/cc/CCPeripheralProvider.java#L19

The lookup returns the same TE regardless of face so I'm not sure exactly what you're saying the problem is.

According to the exact next line, a new object is created for each call. CC API doesn't expect that.

Oh, I see what you're saying..... hm.

Give this a try: http://solder.almuramc.com/downloads/SGCraft-2.0.4-beta-4.jar

Fixed.

Looking good, remember to comment the printf in

SGCraft/src/mod/gcewing/sg/features/cc/CCSGPeripheral.java

Lines 143 to 153 in dea61cd

    
               System.out.printf("CCSGPeripheral.attach: to %s\n", cpu); 
        
               this.world.getMinecraftServer().addScheduledTask(() -> { 
        
                   CCInterfaceTE te = getInterfaceTE(); 
        
                   if (te != null) { 
        
                       te.attachedComputers.add(cpu); 
        
                   } 
        
               }); 
        
           } 
        
           public void detach(IComputerAccess cpu) { 
        
               System.out.printf("CCSGPeripheral.detach: from %s\n", cpu);

That got missed in the official 2.0.4 build, I'll go comment it out so its ready for the next.

	System.out.printf("CCSGPeripheral.attach: to %s\n", cpu);
	this.world.getMinecraftServer().addScheduledTask(() -> {
	CCInterfaceTE te = getInterfaceTE();
	if (te != null) {
	te.attachedComputers.add(cpu);
	}
	});
	}

	public void detach(IComputerAccess cpu) {
	System.out.printf("CCSGPeripheral.detach: from %s\n", cpu);
