[Retired] Door Curtains

Retired, just use animal flaps with my speed fix.

Adds textile and leather door curtains. They have little durability but are very fast to pass through.

To allow the textiles to have a specific opening speed rather than defaulting to 100% (like steel) I had to patch that speed into the vanilla textiles. Anything that also uses the leather and wool bases will inherit the speed. All other textiles will use the default 100%.
In those cases, let me know and I'll do my best to patch them in or poke the other mods' creators, the door speed tag shouldn't cause issues in games without curtains.
