* Add parent / host input curves * reorder some includes to allow particles access to ship.h * Allow modular_curves to deal with functions returning optionals * Add convenience function to return an optional from an objp and an instance type * Add a bunch of particle curve inputs * Fix internal linkage warning * Add hitpoint and shield fraction (albeit limited to ships)
