Added corner pieces so you can make proper corners/edges and cages, etc.

Fixed an interesting Survival bug. You could create any of the designs on the crafting table. But you could only place the ones that had been crafted as the original "Iron Bar." So now that bar is the only one you can craft. But you can use the scroll wheel when placing so it's whatever style you want.

Added blueprints to all the bar types so they can all be made in Survival now. Each takes one Large Stone to create.

Fixed the component set so that these are now destructible. Integrity of 500, meaning that each block takes 13 hits with a sword to break.

Added U-Hook. Two U-hooks attached facing each other make a nice loop. You can then pick up and place another U-Hook inside the loop, and then make a loop out of it. Do that over and over and you can make a real working chain!

Added accurate collision models so that the "Invisible Wall" effect is gone! The grates/bars now work exactly as they look like they should. You can pass, push, or throw thin things through the grille without them just clanging off now. A big step toward realism.

Fixed the "z-fighting" flicker issues by reworking the 3D file and how it mapped the texture. Also working on getting rid of the visible seams between bars. Gotten some fixed, a few more to go.

Added "mipmaps" to texture files. They'll recalculate the textures to be lower resolution as you go farther away from the iron bars. A nice bit of optimizing I had forgotten to do, thanks to ja231c for pointing it out.
