Ephemerides 3.6 (Vintage version) Service Pack 1.2

- The same as above plus the correction for the parallactic angle

I apologize for these, but I'm in a hurry with messy things and I do not have the required mental concentration.

Ephemerides 3.7 (Vintage)

- bug in marker behaviour outside the solar system;
- elevation parallax;
- switch from TDB to UTC realtime systemclock to TDB to UTC simulation also when fast/slow forward/backward buttons/keys are pressed;
this beaviour is standalone, the changing in the time-span setting will not be written on disk.

- substituted the elevation to the power with multiplication;
- Espenak - Meeus (canon) algorithms for the Delta T;
- minor cosmetics;

- basically, the bulletins no longer needs to be set and such menu items could be removed in the next versions.
- returning to realtime (1) will restore TDB to UTC systemclock. Therefore the running times will not be those of the displaced objects.
You must reset the current object's positions by pressing the default current time Celestia's button.
If all this seem a bit messy, you must remember that Celestia's systemclock time is still TDB.

Due to my oblivion, I've forgot to add the correctly revised Dutch language. Thanks to Marco Klunder to have pointed out that. Below the NL language for 3.7 version.

Ephemerides 3.7 (Vintage version) Service Pack 1.0

- fix elongation orientation in printed output;
- minor cosmetics within "ephemPrint.lua";

- updated Free Core Nutation empirical model at July 01 2016. The new table of the yearly amplitudes has been completely revised "due a complete reanalysis after changing the IERS combination strategy" (cit.) and the values are no longer those written within the plug-in up to version 3.7;

- day-current lunar phase is now caught through the relations among elongation/pos.angle of bright limb/illuminated fraction and no longer through the fixed lunar day values.

five files, no user settings/customizations/languages are changed: unpack inside the ephemerides folder and overwrite. Backup of the former files is left to the user.
