listItems console command now sorts its output. WOO!
Fixed some issues resolving block shapes, addressing #702
(There is still a problem with creating new freeform blocks in multiplayer)
Merge branch 'multiplayer' of git@github.com:MovingBlocks/Terasology.git into multiplayer
Fix for jar mods with code.
Adds volumetric fog shadow prototype - approach can be compared to the effect seen in Crysis 3.

* Adds inscattering as a rendering property (default is enabled)
* Adds some minor other rendering related cleanups and tweaks
Moves volumetric lighting post effect to a separate shader so it can be used as a separate post effect (which utilizes a half sized RT).
Adds that all fog related effects get modulated according to the light buffer and/or overall luminance.
* Disables back face culling for shadow rendering (less swiss cheese shadows).
* Tweaks various fog related parameters and tweaks some things on shader side.
