Refactors the nearly completely stateless component "caltrop" into an element. The previous limit on "one message per caltrop per second" has been changed to "one message (about caltrops) per mob per second". This avoids a unique component for each shard of glass, and each cactus in the world, so saves some much needed memory. A message about "sliding over" caltrops has been removed, since it's now intended that you only trigger caltrops if you're not lying down.
