Guffysl/fix metal constraint generator
This branch adds modifications to SetupMetalsMover and MetalContactsConstraintGenerator. MetalContactsConstraintGenerator now has the option to, when multiple ideal angles/dihedrals are specified, constrain to the one value closest to the current value of that measurement instead of creating an AmbiguousConstraint to all provided values. SetupMetalsMover now allows users to specify a residue selector restricting the contacts to be set up and provides a command-line flag to skip adding constraints entirely instead of doing so by setting all the corresponding weight options to zero.
