Climbing wall/gym background

Version 1 - needs the testings - isn't terrible.

Trigger is "climbing_wall"

Also recognises various climbing equipment terms:

Climbing_leggings (basically the same as "yoga pants", but hey, this is climbing!)

Climbing _shoes - depending what other clothing you specify you may need to weight this and out "sneakers" in negative - base model associates shorts/sports bra quite strongly with sneakers it seems

Chalk_bag

Climbing_harness - ymmv, but it actually seems pretty good at making a credible harness that joins together...

As yet "climbing_rope" seems pretty... ropey. Tends to just give standard hemp rope. Will need to work on that one.
