		Change type Atom to RAtom to avoid conflicts with X.
		Offset all uses of xorg, yorg, zorg databse entried with
		fxorg, fyorg, fzorg database entries for UCB bond
		rotation.  Change char* strings to unsigned char* strings
		to allow for extra UCB Angstrom and degree symbols.

[21/08/00]	HJB	applemac.c
		Change from use of toolbar settings to use of RotMode.
		Add new "Settings" menu.

[21/08/00]	HJB	cmndline.c

		the moves control bond rotation, molecule rotation, or
		world rotation, but change from use of toolbar settings
		to use of RotMode

		Add new error message (ErrNoBond) for "Bond for rotation
		not picked".  Add new parameter for alternate conformer
		bond waist radius.  Adapt to fxorg, etc. offsets.  Adapt

		rotation is involved, and add it to RFRotate, RFApply and
		RFInitial.  Add ZRange.  Move main X window definitions
		into this header to facilitate toolbar development.

[21/08/00]	HJB	infile.c, infile.h
