Add configure check for libnova

Use external libnova instead of locally build.
(Upstream libnova has aberration fix as of Jul 9 2015)

libnova-0.13.0/ChangeLog

-ChangeLog
-
-*********** release of 0.13.0
-
-20090514
-	heliocentric_time.h:
-	heliocentric_time.c:
-	test.c:
-		Added heliocentric time corrections calculations.
-
-	Petr Kubanek
-
-20090420
-	julian_day.h: 
-		Removed "#ifndef __WIN32__" to make ln_get_date_from_timet function available in win32
-
-	ln_types.h:
-		Changed tv_sec type from long to time_t to match standard definition
-		Clarified field documentation for ln_nutation
-
-	julian_day.c:
-		Removed "#ifndef __WIN32__" to make ln_get_date_from_timet function available in win32
-		Remove platform-dependent code form ln_get_date_from_sys. The function now simply makes a call to gettimeofday() - a Win32 implementation is supplied in utility.c, and this function is no longer limited to one-second precision under Windows.
-
-	nutation.c:
-		Fixed two values in nutation coefficients table
-		Fixed method used to compute longitude/obliquity offsets. The general form of the calculation is supposed to be, e.g., coeff*sin(D+M+MM+F+O), not coeff*(sin(D) + sin(M) + sin(MM) + ...)
-		Added correct computation for mean ecliptic (Meeus eq 22.2)
-		(These fixes also fix ln_get_apparent_sidereal_time, and affect:
-			ln_get_solar_equ_coords
-			ln_get_solar_ecl_coords
-			ln_get_equ_from_ecl (possibly needs true ecliptic rather than mean)
-			ln_get_ecl_from_equ (possibly needs true ecliptic rather than mean)
-		)
-
-	utility.c:
-		Fixed gettimeofday Win32 implementation:
-			should not add timezone offset - _ftime_s and gettimeofday both work in terms of seconds since Jan 1 1970, UTC
-		Added some explicit casts to remove compile warnings
-		Cleaned up implementations of ln_deg_to_hms, ln_rad_to_hms, ln_deg_to_dms, and ln_rad_to_hms

-20070116
-	libnova is now ported to Win32 with the following changes.
-
-	-src/julian_day.c
-
-	Added preprocessing directive for POSIX header (sys/time.h) exclusion	for Win32 compilation.
-	Changed ln_get_date_from_sys to be compatible with Win32.

-	Changed libnova.h include to libnova/libnova.h.
-
-	-src/utility.c
-
-	Added preprocessing directive for POSIX header (unistd.h) exclusion for Win32 compilation.
-	Added functions gettimeofday, gmtime_r, and strtok_r to substitute for their POSIX coupterparts.
-	Added functions cbrt, nan, and round to subsistute, in C89, for their C99 counterparts.
-
-	-src/libnova/ln_types.h
-
-	Added definitions of struct timeval and struct timezone to subtitute in Win32 for their POSIX counterparts.
-
-	-src/libnova/utility.h

-	Add various _next_ & _horizon functions.
-	Add ln_get_motion_body_rst_horizon function.
-	Fix dynamic time diffs in rst functions - remove dynamical time
-	correction from object_rst, where it's not needed, use it only for
-	nr, nt and ns corrections (interpolation coeficient) in body &
-	motion_body variants.
-	Add dm corrections for object calculation, as 0.01 is ~ 10 minutes.
