Added Heatwave effect to the Particle Emitter. You can set the "opacity" to 0 and you will have only the Heatwave effect.

New particles added (and changed some of the old ones) for the Particle Emitter!
Removed the fallback block for all the blocks.
Fixed shadow issue with the SpotLight. It now won't cast shadows when the SpotLight is set to "nomal" visibility. Set the block to "hidden", "sphere", or "box" to see shadows.

Added TextBlock !
Added option to GlassBlock so it starts OFF.

Added physics to particles!
They cannot influence other objects (you can't use them to push other blocks for example) but they are influenced by them (they will bounce off your machine).

SpotLight in directional mode can now cast shadows.
Fixed the collider issues with SpotLight and ParticleEmitter: if you turn the "hide" option ON, it will properly disable the collider as soon as the simulation starts, thus your machine will not break if you place the blocks inside other blocks and make them hidden.

Fixed the "No collider" toggle not hiding the block during simulation for the Particle Emitter Block.
Removed "Rainbow mode" from the glassblock and implemented the smooth version of the strobe mode (which was already being used by the spotlight block). This smooth version enables you to make your own rainbow mode.

-Joints are now stronger for SpotLight and ParticleEmitter blocks.
-May or may not have fixed MultiPlayer issue where Clients cannot see the host's lights.

SpotLight block:
-Fixed the "default" slider options not hiding when setting mode to "auto" for the various options (Brightness, Cone Angle, Color)
-Removed the block's update when entering build mode. Now if you set the mode to something other than Normal, the block will still show, alongside the Sphere or Box depending on how you want the block to show. It is a bug, but I can't fix it at this time since the only other way I found is to remove the Brightness/Color preview you get when you change the sliders in build mode, which I think is better to keep.
-Hopefully fixed issues in MultiPlayer that prevented the block from showing or not working properly.

SpotLight block:
-Added "Box" appearance, which functions just like "Sphere" but looks like a box.
-Fixed Colliders not being disabled when "hidden", "Sphere", or "Box" were selected for the appearance.
-"Fixed" the appearance not being properly shown when entering build mode from a simulation.

Fixed the missing "default" options for the SpotLight block.
