Added more builtin inverse conversion functions

Browse Source 
Added builtin functions to convert between degrees, minutes and
    seconds and degrees under the config("mod") round rules:

	dms2d(d, m, s [,rnd]) - convert deg, min, and secs to deg
	dm2d(d, m [,rnd]) - convert deg, min to deg

	See help/dms2d and help/dm2d.

    Example:

	; print dms2d(12, 20, 44.16);
	12.3456

	; print dm2d(3601, -25.5594);
	0.57401

    Added builtin functions to convert between gradians, minutes and
    seconds and gradians under the config("mod") round rules:

	gms2g(g, m, s [,rnd]) - convert grad, min, and secs to grad
	gm2g(g, m [,rnd]) - convert grad and min to grad

	See help/g2gms and help/g2gm.

    Example:

	; print gms2g(12, 20, 44.16);
	12.3456

	; print gm2g(4001, -25.5594);
	0.57401

    Added builtin functions to convert between hours, minutes and
    seconds and hours under the config("mod") round rules:

	hms2h(h, m, s [,rnd]) - convert hours, min, and secs to hours
	hm2h(h, m [,rnd]) - convert hours, min to hours

	See help/hms2h and help/hm2h.

    Example:

	; print hms2h(12, 20, 44.16);
	12.3456

	; print hm2h(241, -25.5594);
	0.57401

NAME
dm2d, dms2d - convert degrees, minutes, and seconds to degrees
SYNOPSIS
dm2d(d, m [,rnd])
dms2d(d, m, s [,rnd])
TYPES
d real
m real
s real (defauls to 0)
rnd nonnegative integer, defaults to config("mod")
return degrees
DESCRIPTION
Convert degrees, m minutes, and s seconds returning degrees.
The return value in degrees, is quivalent to the following:
mod(d + m/60 + s/3600, 360, rnd);
Depending on the rounding mode, the return could be a real value
in the interval [0, 360) or a real value in the interval (-360, 0].
For the default round mode, the return value is in the interval [0, 360).
A missing rnd defaults to config("mod").
For more information on the effects of rnd, see "help mod".
The dm2d(d, m, rnd) builtin is an alias for dms2d(d, m, 0, rnd).
EXAMPLE
; print dm2d(203, 325.5594);
208.42599
; print dm2d(3601, -25.5594);
0.57401
; print dm2d(-923, -25.5594);
156.57401
; print dms2d(12, 20, 44.16);
12.3456
; print dms2d(123.456, -345.68, 4.08);
117.6958
; print dms2d(-65, -40, -44.4);
294.321
; print dm2d(203, 325.5594, 1);
