Slight Makefile tweaks, README edits and site update

  - #64: `NOVAS_TAI_TO_TT` definition had wrong decimal in last place, thus was 3 ms off from what it should have been.
    (thanks to kiranshila)
 
- - #68: `readeph_dummy()` dummy implenetation in `readeph0.c` called non existing error handler function.
+ - #68: `readeph_dummy()` dummy implementation in `readeph0.c` called non existing error handler function.
 
 ### Changed
 
- - #59: For major planets (and Sun and Moon) `rad_vel()`, `rad_vel2()`, `place()`, and `novas_sky_pos()` will include 
-   gravitational corrections to radial velocity for light originating at the surface, and observed near Earth or else 
-   at a large distance away. The corrections can be skipped for `rad_vel()` / `rad_vel2()` by setting `d_src_sun` 
-   negative.

+   Earth or else at a large distance away. These corrections, along with those for the Solar potential at the source, 
+   may be skipped for `rad_vel()` / `rad_vel2()` by setting `d_src_sun` negative.
 
  - #55: Use relativistic formulae to add/difference velocities (i.e. change velocity reference frame).
 
  - #60: Moved SuperNOVAS-only functions to a separate `super.c` module to alleviate the bloating of `novas.c`, which
    can still be used as a self-contained, standalone, NOVAS C replacement for legacy applications if need be.
 
  - #62: Improve debug mode error tracing when NAN values are returned, so the trace indicates NAN rather than a bogus
-   integer before.
+   integer return value before.
 
  - #66: Various tweaks for C/C++ best practices (by kiranshila)
