Some work on particle effects (adds particle effects at set range in cardinal directions (N,S,E,W + top and bottom) (note: an additional block is still powered, as would be the case with redstone dust *This is a feature, not a bug, as it allows one to visualize the redstone signal pathway rather than show which blocks are powered, which can
be confusing*)
Also:
- Bump version to 0.8.1-alpha
- Bump Forge to 10.13.2.1230
- Removed unnecessary references directory (this was moved to the src tree already...)
