Fixed an error.

How to Use:
Tool:
Primary: Connect two points with a climbable rope
Secondary: Create a hanging rope

While Hanging:
Jump: Go up the rope
Crouch: Go down the rope
Crouch on ground: Get off the rope
Crouch+Jump: Jump off the rope

Settings:
Maximum Length of Rope - The maximum length the rope can be when creating a hanging rope. The rope can be shorter because it creates the rope so that the length is slightly above the ground.
Constant, Damping, Relative Damping - Same as elastic constraint. Can affect how well the climbable ropes work.
Rope Width - The width of the rope.
Material - Material the rope will appear as.

Installing Fresh:
Extract to the addons folder.

Upgrading from older version:
Delete Folder - garrysmod/garrysmod/lua/entities/climb_rope
Delete Folder - garrysmod/garrysmod/lua/entities/player_constraint
Delete File - garrysmod/garrysmod/gamemodes/sandbox/entities/weapons/gmod_tool/stools/climbrope.lua

Suggestions, comments, and bug information appreciated to improve it.
