Update from Upstream
Double chest rendering glitch fix.
Double chests whose primary block was outside the screen frustum would cause the entire chest not to render because Forge wasn't recognizing ChestTFC as a chest.
Chest Open/Close Glitch
Forge code conflicted with TFC code for chests. The original code looked for players using vanilla Chests and finding none would close the chest. The TFC code wouldn't re-run the check for active players. This made chests glitch open and play closing sounds every time they synced, but would work perfectly if opened and closed between syncs.
