Adds a Rope and Chain

Adds a rope and chain and climbable blocks

Adds Rope and Chain A Climbable block with custom climbing properties

Feature Feature Idea: placing rope down on a rope block will extend the rope would help with placing lots of rope across chasms and into deep caves

they are also zig components in the block which means adding new ropes or ladders is easy

ok the code and assets are good to go and load properly i just need to fix formatting

[Vinywar123]

welp no clue what the formatter is asking me to change now

[Vinywar123]

you did it correctly enough thanks for your help that fixed it

Climbing feels very floaty, when I stop pressing space/shift it takes a bit to slow to a complete stop. Which is not something that happens if you climb something IRL.

Also, if you're adding climbing, you should add ladder blocks, which already have block and item textures in the files.

[Vinywar123]

those can be added with the climbable and climbing speed propties to the ladder

ok updated the physics

I think this should wait until the physics refactoring by @codemob-dev is done (see #2121) which touches a lot of the changed code.
