Minor tweaks to FastDesign and to the ReadResfile TaskOperation
-- Adding support to FastDesign for clearing the pose if it contains D-amino acids.
-- Adding an explicit copy constructor to the ReadResfile TaskOperation that clones the ResidueSelector, if one is present.
-- Adding explicit set_residue_selector() and residue_selector() functions to the ReadResfile TaskOperation.
