Fix doxygen labels in EOS_Wright_full and _red

  Changed recently added doxygen labels in the two newly added EOS_Wright_red and
EOS_Wright_full modules to avoid reusing names that were already being used
by EOS_Wright.  All answers are bitwise identical, but the doxygen testing that
had been failing for the previous 5 commits is working again.
