Justify Lasers

# 2.0.0-alpha.26

Changes since **2.0.0-alpha.21**.

- Added small and multiblock Solar Concentrators with sun tracking, daylight-dependent output, redstone control and privacy. The large collector has four lower resonators and a selectable beam output.
- Added luminous flux (lm), LM-powered crystal growth and the Beam Combiner, which merges beams with 5% loss.
- Made all five laser components placeable; added solar absorbers, laser-absorbing glass and an Electric Motor.
- Added tablet-schematic loot, tablet assembly and schematic copying; restored the Fuel Generator recipe and added tablet charging.
- Reworked the Fuel Generator model and thermal output: fuel-specific heat limits, slow heating and 3× faster cooling. Lava peaks at 1200 °C, 95% efficiency and 128 FE/t.
- Added JEI recipe shortcuts and layered multiblock construction guides; updated recipes, held schematics and English/Russian documentation.
- Removed the external-tech-mod requirement and the Electric Smelter. All remaining content is available standalone.

Back up worlds before updating. Empty old Electric Smelters first; earlier solar structures need the new layout. Guns, turrets and sabers still do not consume energy.
