CubicChunksCompatibilityHelper

Initial Release

Added modules:

• Changes ActuallyAddition's Vertical Digger to mine through y=0, down to a maximum depth relative to the Digger, or to a minimum absolute depth (y-level), whichever is higher. Hover text when looking at the Digger also renders correctly.
• Changes RangedPumps' Ender Pump to work across y=0, similarly to how ActuallyAddition's Vertical Digger was changed.
• Adds a variation of Worley's Caves' cave generation that works in cubic world types (e.g. CubicWorldGen), and extends below y=0, albeit without minimum/maximum y-levels.
