This can be implemented in C4Script very easily.
Removed OCF_LineConstruct, ObjectComLineConstruction, Defcore LineConnect, Line types, Line related IDs.
Changed LineAttach, is now a property of the object to which the line should be attached.
Updated documentation.
Removed power lines, power connects, energy rule, power OCFs, Energy command, C4Script CheckEnergyNeedChain and EnergyCheck, Action EnergyUsage and documentation.
This is obsolete with new melee implementation and other authors should either use that or make something unique themselfs. Removed DFA_FIGHT, C4Script FnFightWith, ObjectActionFight, NoFight, OCF_FightReady, Fight Physical
