INVENTORY (the MARRIAGE): the old and new inventory system finally live together happily

SMELTER:

turns out the smelter not working was just the inventory hiding things from it. Fixed tho.

BUILD MODE (it did literally nothing):

found out buildItems was an empty list, so pressing the build key did absolutely nothing except make me feel stupid, istg it had stuff before also the placement key was set to 1 which was fighting with the hotbar, so its back to B.

SAVE SYSTEM: inventory was never being saved because the Inventory manager that was supposed to save disappeared. also fixed machineType on the mini drill so machines dont all respawn as the same drill on load.

MINI DRILL (quality of life, battery edition):

~5 minutes of drilling. now it works until the battery dies. the UI also shows name + battery.

Bug fixes:

Everything works better now, still has the same bugs since the last time tho, less severe but still there.

current issues:

-machine internal state (battery, smelter input/output) –isnt saved yet — position yes, battery no.
-building snap is still mid
-cables still dont have a real material

whats next:

conveyors actually moving items visually, nuclear reactors (3.6 Roentgen), proper build UI instead of scroll wheel, and like the game itself.
this game is starting to seem like an indie solo game and not an ugly prefabs spam.
