- disable locales via use of LC_ALL=C in all shell scripts
   (which will hopefully make sorted lists more consistent
    between people running with different locales).
 - remove redundant files from PW, NMR_new, VdW, VIB;
   rename subroutines if their functionality is noI
   unchanged from the original source it was taken from.
 - corresponding updates to Makefiles and dependencies.
 - whitespace cleanups (eleminate remaining tabs).
 - a few more float->DBLE
