Recommendation is to avoid using the year nomenclature as this
information is already encoded in the git repo. Avoids needing to
repeatly update.
Also updates AUTHORS.txt from current repo with contributor names

We need to use a "C" locate to read/write files, and therefore switch the locale.
Removing use of setlocale( LC_NUMERIC, "C" ) and use only
wxLocale( "C", "C", "C", false ) was too fast: on linux it breaks the env vars.
on MSW
using setlocale( LC_NUMERIC, "C" ) generates an alert message in debug mode,
and this message ("Decimal separator mismatch") must be disabled.
But calling wxLocale( "C", "C", "C", false ) works fine
On unix:
calling wxLocale( "C", "C", "C", false ) breaks env vars containing non ASCII7 chars.
these env vars return a empty string from wxGetEnv() in many cases, and if such a
var must be read after calling wxLocale( "C", "C", "C", false ), it looks like empty
So use wxLocale on Windows and setlocale on unix
