Discontinuous Beacon Beams

• Fixed an issue where a beam wouldn't be hidden or unhidden as expected if the first block in its path was white stained glass or clear glass (#6)
• Theoretically improved the way beams are disabled when "Enable beacon beams" is false
  • performance should be (minutely) improved
  • compatibility should be slightly better (other mods' non-beam beacon rendering changes are more likely to remain enabled)
• moderate internal changes
