From MageKing17 and me: Fix for Mantis 3128: Docking related crash - dock_list isn't initialized This patch makes the copy constructor and the assignment operator of the object class private as it contains members that should not be copied.

Adding "interceptable", "turret interceptable", and "fighter interceptable" weapon flags.

These allow munitions to be attacked by the AI without needing to set the "bomb" flag; "turret interceptable" means it can be attacked by turrets, "fighter interceptable" means it can be shot down by fighters, and "interceptable" sets both flags simultaneously. Requested by Rheyah.
