Added ability for entities to request previous frame broadcasts
Removed optimizations for Machine.removeEntity and Machine.removeManagedAbstraction
Added W and M
Added hasTemperature attribute
Added ice and steam
Fixed potential bug with fluid.doesCollideWith
Added friction_extralight force type

This was causing fluids to incorrectly ignore slopes.
Temperature can now be raised by lasers
Ice doesn't block lasers anymore, and will melt when hit by one
Water and steam are now clear
Tweaked water example
Added comments to fluid flowing code
Changed fluid flow force type

This was causing water to sometimes ignore slopes.
Test machines: Added ice compressor
Fixed entities do not collide with fixed entities anymore
Editor: Fixed transparency rendering
solid.applyForce now combines force amounts when applying a force of equal type

This was causing water not to flow properly.
Added “background2” depth level, applied it to water
Changed steam background opacity
Changed fluid pressure simulation to take fluid types into account
