Hi Rudolf,

yes, it still being developed, the developers' repository can be browsed here
    http://svn.savannah.gnu.org/viewvc/?root=texmacs
Recent stable builds are available from  ftp://ftp.texmacs.org/TeXmacs/tmftp/

As for your main question, I know this is possible and I have seen it 
discussed somewhere. Unfortunately I can't find it anymore.
Probably 
TeXmacs-1.99.4.app/Contents/Resources/share/TeXmacs/packages/standard/std-math.ts
 is a good start (macsOS paths)
Hopefully someone can come up with a definite answer…
