[IGSMAIL-6259] Update: rcvr_ant.tab, antex14.txt

Dear Colleagues!

Due to the emergence of additional GNSS an update of the ANTEX format
description became necessary. The new version 1.4 includes satellite
system flags and frequency number codes for Compass, QZSS and SBAS.
Besides, the satellite numbers for Galileo were defined (SVID and GSAT
number) and the sorting of antenna calibrations within IGS files was
explained. Moreover, several suggestions as regards the clarification of
the description from recent years were considered.

The updated format description is available at
ftp://igs.org/pub/station/general/antex14.txt

At the same time, names for several satellite antenna types were added
to rcvr_ant.tab:

| GALILEO-0A           |  Galileo In-Orbit Validation Element A (GIOVE-A)      |
| GALILEO-0B           |  Galileo In-Orbit Validation Element B (GIOVE-B)      |
| GALILEO-1            |  Galileo IOV     : GSAT 0101-0104                     |
| QZSS                 |  QZSS            : SVN 01                             |

We would like to thank Francisco J. Gonzalez from ESA and Hiroaki
Tateshita from JAXA for their cooperation!
