* Lattices no longer block all downward movement out of their turf, they only block downward falling out of their turf.
* Objects are once again pullable on catwalks (not 100% sure why they were not, but had to do with the falling code calling Move())
* Falling on top of a mob will no longer do an infinate loop of swapping places vertically.
* Fix falling to check if movement actually succeeds before taking damage from falling.
* De-snowflakes how objects prevent you from falling out of their turf (catwalks and latticue)
* Improved the messaging and the way falling procs are called to make it more flexible and possible to hit things in a turf before the turf itself.
* Catwalks are an upgrade to lattice; instead of just a framework of wires its a mostly solid grid walkway.
* They are semi-transparent so you can see wires/pipes below them a bit.
* Smoothly auto-joining sprites to look proper.
* Constructed by upgrading lattice; like lattice it will stop you falling if build over an open space.
* Changes from Eris: Converted << to to_chat(), fix redraw on Destroy(), Fix color macros in text.
