Updated the data files to use Keen's new block/fire/effects system.

This has meant that I had to change some of the basic particle effect to fit the new system. I've tried to keep the fire looking and sounding as close as possible to how it used to. Any changes should be superficial and not easily noticed.

You might have to turn this on/off to activate the new system. Or possibly even pick it up and lay it back down in place. But it should work just the same as before.

Updated Wooden Chest blueprint component from old CargoContainer type to new CubeBlock type so beacon could be buildable again in Survival post 0.4.14.

Noticed also that position was off (hovering a bit) when placed on large-block item like a stone cube floor. I've readjusted so it sits nicely on the ground.

Previously-placed beacons will now be smushed about 0.25 meter into the ground. If so, just pick up and re-lay.

Adjusted sound file folder path so sounds would continue working post 3/14/2017 game update
